Welcome!

Welcome! Thank you for joining our research experience. Below you will find a brief outline of what we shall be doing over the next few months and the motivation behind it. 

Introduction to the Seminar: This pilot program will give participants from all backgrounds the opportunity to participate as a team member in a genuine published research opportunity using the technique of speckle interferometry. Emphasis items will include astrometry, short period binaries, and historical data.

Goals:

  • Produce a cohort of researchers familiar with the techniques of speckle interferometry.

  • Published research papers written by participants doing the best possible science at this

level.

  • Understand the capabilities of BARO (the telescope we shall be using).


Motivation: Although Red Dwarf (RD) stars—spectral types late K and M on the Main Sequence—are the most common stars in the Milky Way, they are intrinsically faint and more difficult to observe than earlier types, so their population, even within the solar neighborhood, has not been fully explored. The RECONS survey has completed the census of all stars within 10 parsecs of the Sun, and the campaign to discover all the stars within 25 parsecs is continuing. Recent advances in low cost, red-sensitive, high speed but low-read-noise, back-side illuminated CMOS cameras has enabled the study of brighter RD stars with small telescopes.

 

A campaign to observe the brightest nearby binary systems containing a Red Dwarf was initiated with the Orange County Astronomers 22-inch telescope in 2019 (Wasson et al. 2020, RDSN-1). This campaign was continued in 2020 utilizing the 11-inch telescope at the FIRO, the Fairborn Institute Robotic Observatory (Altunin et al. 2020, RDSN-II). Two further continuations were started in 2020 (RDSN-III and RDSN-IV) focusing on RD’s with shorter periods. Papers are currently being written.

 

The teams in this research experience shall continue this campaign and produce the RDSN-V and RDSN-VI Papers utilizing the 0.5m Boyce-Astro Robotic Observatory (BARO) telescope in Southern California. The produced papers shall include the following:

  • New Speckle Observations of 10 Short-Period RD Double Stars - Astrometric and

Photometric

  • Historical Observations from UKIRT and PANSTARS

  • Discussion on the Binary Nature of these doubles

  • Discussion on the capabilities of BARO

 

Schedule:

  • Starting May 28th, Meetings shall be held Fridays from 6:00-7:00 pm PT

    • Recorded for those unable to make it

    • A combination of instruction, mentoring, and guest talks

    • Weekly Office Hours will be held by assistant mentors

    • Teams are strongly encouraged to meet independently outside of weekly meetings.

 

Course Platforms:

  • Discord – Office hours, team meetings, discussion

  • Zoom – Weekly group meetings

  • FIRO Website – Student Portal with all course resources (www.FairbornInstitute.org

 

Course Staff:

  • Ivan Altunin – Research Experience Director, Primary Mentor

Meeting: Friday, May 28th, 6:00-7:00 PT (Zoom link sent through Discord)

Summary: This module shall walk you through all of the steps needed to set up the software used for this course and setting up groups. 

1. Download Software: The software that you need to install is OS specific so please read the instructions carefully. 

 

  • Set up repository: It is recommended you create a folder somewhere on your computer titled “SIRE Tools” or something similar for easy access to all of these tools. As you follow the instructions below put the downloads or a shortcut to them within this folder. 

 

  • Remote Desktop Access Software: This shall be used to interact with the telescope and take observations later on. This will also be how initial data processing is done and how Mac users can use the software if they opted out of setting up a Windows 10 VM.

    • Install: TBD

 

  • Download Speckle Toolbox (Dave Rowe): If you are running Windows or a Mac with a Windows VM, download Speckle Toolbox from the resources tab. Skip this if you are on a Mac and opted out of setting up a Windows 10 VM. This is how the speckle data will be processed. 

  • Download the Gaia Double Star Selection tool (Dave Rowe): If you are running Windows or a Mac with a Windows VM download the GDS Selection from the resources tab. This is how we shall generate a target list. 

  • Group Assignment Form: Please fill out the form to be sent out in the Discord server to help us determine how to best form groups. ​

Module 1: Intro to Speckle

Start: June 4th | Finish: June 10th | Estimated Time to Complete: 1-2 hours

Meeting: Friday, June 4th, 6:00-7:00 PT (Zoom link sent through Discord)

Summary: This module shall walk you through all of the basic knowledge you need for speckle research of double stars, specifically red dwarfs. 

 

Teams: During Friday’s class, you should get assigned as a member of your team. In addition you will get assigned your team role on the Discord server. This will enable access to both your Team text chat and voice chat. 

 

Readings: We shall cover everything you need to know in our group meeting, however, if you still have questions afterward please feel free to review the following resources as needed:

 

Assignment: Meet with your team at least once during the week and work together to write: 

  • One sentence summarizing Double Stars and why we study them.

  • No more than two sentences Summarizing Speckle Interferometry.

    • Consider calculating and including the Rayleigh limit for the 0.5 m Boyce-Astro Robotic Telescope in the Sloan r’2 Filter (626 nm)

 

  • And finally, one sentence summarizing Red Dwarfs.  

    • In future modules, we will go over why we are studying Red Dwarf doubles in the first place. 

 

These sentences will later serve as a starting point for your paper introduction and will help ensure you understand the material and motivation behind your research. When this is complete, send your sentences to the Course Staff in the Discord Server in your Team Chat.

Module 3: Targets and Start Data Acquisition

Start: June 19th | Finish: June 25th | Estimated Time to Complete: 1-2 hours

Meeting: Friday, June 18th, 6:00-7:00 PT (Zoom link sent through Discord)

Summary: This module shall walk you through how to generate a target list for your team. As well as general observing instructions.

 

Observing: For the next 3 weeks we shall be observing on most days with good weather, assuming that the telescope cooperates. If you haven’t already please sign up for some observing sessions through the link sent out by email. These observing sessions are optional although highly recommended to attend if you want to get the most out of the course. To attend simply join our weekly Zoom, a reminder will also be sent to those who signed up several hours before. On your third night you might be able to control the telescope under the supervision of another experienced observer.  

Generating a Target List: These instructions make use of the GAIA Double Star Selection tool which Windows users should have downloaded earlier. If a team member would like to go through this process and does not have it downloaded please coordinate so that one member can share their screen/process with the other. Remote access to this software will be available in about 2 weeks for future reference. 

Criteria:

  • RA Limits: 14, 19 hrs

  • DEC Limits: - 20, 50 hrs

  • Gmag0 and Gmag1 limits: Both 6, 12

  • Delta Mag: 0, 2

  • Sep: 0.5, 2

After running the query “Write All Records to CSV File” being sure to “Include WDS Data” and “Write all Records”.


Calculate the color index for each star by opening the list in excel and subtracting BPmag0 - RPmag0 and BPmag1 - RPmag1. This will be the color index for the primary and secondary respectively. Choose 3 stars with a color index greater than 1.8 and those will be your team's Red Dwarfs. Unfortunately not many more are viewable, or at least weren't detected by GAIA in this part of the sky. Choose 3 other bright targets (6-8 mag primary) from the list that you think might be interesting! When your team has a list email it to the course staff by Friday the 25th for approval. 

 

Observation sessions before the 25th will collect data on other stars that should give guaranteeable astrometric results to be distributed to the different teams later. 

Assignment: Meet with your team at least once during the week and work together to write: 

  • The target selection section of your paper

  • Attend any observation session you signed up for
