I am honored and extremely delighted to have been selected as a 2022 Hubble fellow! I will be joining UC Berkeley and Prof. @jlu_astro's group to continue the search for non-interacting black holes after I defend my PhD at OSU Astronomy in the summer.

My colleague Kris Stanek won a Guggenheim Fellowship for his work on ASAS-SN and all things variable! Congratulations to Kris! OSU Astronomy CCAPP Citizen ASAS-SN artsandsciences.osu.edu/news/2022-gugg…

Need a light curve ANYWHERE on the sky? Use ASAS-SN Sky Patrol asas-sn.osu.edu to get a light curve for any point on the sky, with >1,800 to ~7,600 data points (median is ~3,200!)

Do you like variable stars? We LOVE variable stars! So, we have discovered more than 100 THOUSAND new ones! "The ASAS-SN Catalog of Variable Stars X: Discovery of 116,000 New Variable Stars Using g-band Photometry" arxiv.org/abs/2205.02239 led by Collin Christy and Tharindu Jayasinghe.

We have a new paper on astro-ph today! This work outlines our search for variable stars in ASAS-SN's newer g-band data. We used features derived from Gaia, 2MASS, and AllWISE to examine the variability of ~ 55 million stars with g<18 mag. arxiv.org/abs/2205.02239

I am excited to share our new paper that is on astro-ph tonight! We fit the ASAS-SN V- and g-band light curves of more than 30,000 detached eclipsing binaries using PHOEBE: arxiv.org/abs/2205.05687

How it started How it is going ESA Gaia

I did the thing!! I defended my PhD last week and we celebrated today after I came out of COVID isolation! We had ice cream cake, champagne and unicorns to celebrate my PhD! I am super thankful to Kris Stanek, Chris Kochanek and Todd Thompson who are the best advisors!! Yay!

Our interactive ASAS-SN eclipsing binaries database is now live! Many thanks to Wesley Giles (Wesley Giles) for his amazing work on this: asas-sn.osu.edu/binaries

(NEW) ATel 15531: An Update on ASASSN-21qj: A Rapidly Fading, Sun-Like Star; Back With a Vengeance... astronomerstelegram.org/?read=15531

An update on this Sun-like star just posted to The Astronomer's Telegram ! Following its dimming event last year, it is back with a vengeance and varying quite dramatically. BVI photometry suggests it could be dust obscuration ....maybe 👀 astronomerstelegram.org/?read=15531

I am excited to share our second ASAS-SN eclipsing binary catalog paper that is now on astro-ph! Here we explore the properties of 766 eclipsing binaries with “extra physics” in their light curves: arxiv.org/abs/2210.06486

It is time to yet again vote for the "Astro Plot of the Week" - pick one: - Plot from Rowan et al. (arxiv.org/abs/2210.06486) - Plot from Hogg et al. (arxiv.org/abs/2210.07210) The poll is below - vote now, and spread the word!

1/ Cao, Pinsonneault, & van Saders (2023) arxiv.org/abs/2301.07716: If stars experience an effect called core-envelope decoupling---where their envelopes spin down independently of their cores for a time, strong radial shears may drive an alternative dynamo mode. (Submitted, ApJL)

Citizen ASAS-SN Congratulations to the Citizen ASAS-SN project and all the volunteers, you just passed 1.5 million light curve classifications!

My current research assistant position is now hiring as I’ll be leaving for graduate school! I can’t recommend this job enough, apply or spread the word.

Did you know that ASAS-SN data are used in, at least, 200 papers per year? That is comparable to an 8-m class telescope, at a small (~0.05 or less) fraction of the yearly operating cost. Yes, we rock! ui.adsabs.harvard.edu/search/q=citat…
