JOSEPH W BARNETT
Hi, I’m Joseph (Joe) Barnett. Welcome to my personal website.
I have Bachelor of Science degrees in mathematics and physics and a Master of Science degree in physics. This site is built to showcase the work that I’ve been involved with.
Below you’ll find a brief description of each research project I have participated in and a portfolio of my published work and GitHub projects, as well as a contact form.
RESEARCH
- November 2015 – December 2018: Membership determination of open star clusters Berkeley 66 and M67, using data from WEBDA, Gaia, and Pan-STARRS (Austin, TX).
- May 2017 – August 2017: Imaging active galactic nuclei at radio frequencies using Difmap (Wuerzburg, Germany).
- January 2019 – December 2019: Membership determination of two overluminous white dwarfs in NGC 6633 using Gaia data (Commerce, TX).
- May 2019 – July 2021: Construction of the first semi-empirical initial-final mass relation for white dwarfs with helium atmospheres (Commerce, TX).
-
The Initial-Final Mass Relation for Hydrogen-deficient White Dwarfs – When I submitted my master’s thesis it was concluded that more data were necessary to constrain the initial-final mass relation for white dwarfs with helium atmosphere. These data became available shortly after I graduated, and this study makes use of these data to obtain more precise results.
-
Double degenerate candidates in the open cluster NGC 6633 – This is a conference proceeding for a talk I gave at IAUS 357 on two overluminous white dwarfs in NGC 6633.
-
Determination of the Initial–Final Mass Relation for White Dwarfs with Helium Atmospheres -This is my master’s thesis where I constructed the first semi-empirical initial-final mass relation for white dwarfs with helium atmospheres. I was awarded a Master of Science in Physics in December 2020.
PUBLICATIONS
GITHUB
- Gaia to CSV – Searches the Gaia Database and automatically downloads the results as a CSV file.
- Numerical Methods Calculator – A calculator which implements various numerical methods and includes support for many special functions. Includes tools for root finding, interpolation, differentiation, and integration, as well as an ODE solver.
- Collatz – Generates the hailstone sequence for up to twenty integers using parallel programming and returns the total stopping time and upper bound for each.
