Precise and Accurate Mass and Radius Measurements of Thirty Galactic Metal-Poor Stars in Detached Eclipsing Binaries
D. M. Rowan, K. Z. Stanek, C. S. Kochanek +4
Detached eclipsing binaries have long served as fundamental benchmarks for making direct comparisons with stellar models. By combining the light curve and radial velocity orbit of…
Astronomical Cardiology II: A Search For Heartbeat Stars Using APOGEE and TESS
Jowen Callahan, D. M. Rowan, C. S. Kochanek +1
Stellar binaries in short-period, highly eccentric systems with significant tidal deformations near pericenter, also known as heartbeat stars, are a laboratory for studying dynamic…
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…
