The HST Ultraviolet Spectrum of V723 Mon: Additional Evidence of a Stellar Companion
C. S. Kochanek, K. Z. Stanek, T. A. Thompson +1
V723 Mon is a high mass function (f=1.7Msun) single lined spectroscopic binary with a red giant primary that Jayasinghe et al. (2021) suggested had a black hole as its massive comp…
ASASSN-24fw: An 8-month long, 4.1 mag, optically achromatic and polarized dimming event
R. Forés-Toribio, B. JoHantgen, C. S. Kochanek +20
We discuss ASASSN-24fw, a 13th-magnitude star that optically faded by mag starting in September 2024 after over a decade of quiescence in ASAS-SN. The dimmimg…
Astronomical Cardiology: A Search For Heartbeat Stars Using and
Jowen Callahan, D. M. Rowan, C. S. Kochanek +1
Heartbeat stars are a subclass of binary stars with short periods, high eccentricities, and phase-folded light curves that resemble an electrocardiogram. We start from the $\textit…
A Systematic Search for Big Dippers in ASAS-SN
B. JoHantgen, D. M. Rowan, R. Forés-Toribio +6
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplan…
The Unhurried Universe: A Continued Search for Long Term Variability in ASAS-SN
Sydney Petz, C. S. Kochanek, K. Z. Stanek +4
We search a sample of 5,685,060 isolated sources in the All Sky Automated Survey for SuperNovae (ASAS-SN) with 14.5<g<15 mag for slowly varying sources with brightness changes larg…
Citizen ASAS-SN Data Release II: Variable Star Classification Using Citizen Science
O. Kotrach, C. S. Kochanek, C. T. Christy +5
We present the second results from Citizen ASAS-SN, a citizen science project for the All-Sky Automated Survey for Supernovae (ASAS-SN) hosted on the Zooniverse platform. Citizen A…
