Citizen ASAS-SN Data Release I: Variable Star Classification Using Citizen Science
C. T. Christy, T. Jayasinghe, K. Z. Stanek +7
We present the first 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 AS…
Discovery of a Highly Eccentric, Chromospherically Active Binary: ASASSN-V J192114.84+624950.8
Zachary S. Way, T. Jayasinghe, C. S. Kochanek +5
As part of an All-Sky Automated Survey for SuperNovae (ASAS-SN) search for sources with large flux decrements, we discovered a transient where the quiescent, stellar source, ASASSN…
ASASSN-21co: A detached eclipsing binary with an 11.9 year period
D. M. Rowan, K. Z. Stanek, Z. Way +10
We use ASAS V-band and ASAS-SN g-band observations to model the long-period detached eclipsing binary ASASSN-21co. ASAS observations show an eclipse of depth V ~ 0.6 mag in April o…
High Tide: A Systematic Search for Ellipsoidal Variables in ASAS-SN
D. M. Rowan, K. Z. Stanek, T. Jayasinghe +5
The majority of non-merging stellar mass black holes are discovered by observing high energy emission from accretion processes. Here we pursue the large, but still mostly unstudied…
The Loudest Stellar Heartbeat: Characterizing the most extreme amplitude heartbeat star system
T. Jayasinghe, C. S. Kochanek, J. Strader +16
We characterize the extreme heartbeat star system MACHO 80.7443.1718 in the LMC using TESS photometry and spectroscopic observations from the Magellan Inamori Kyocera Echelle (MIKE…
The search for failed supernovae with the Large Binocular Telescope: a new candidate and the failed SN fraction with 11 yr of data
J. M. M. Neustadt, C. S. Kochanek, K. Z. Stanek +5
We present updated results of the Large Binocular Telescope Search for Failed Supernovae. This search monitors luminous stars in 27 nearby galaxies with a current baseline of 11~yr…
The Changing Look Blazar B2 1420+32
Hora D. Mishra, Xinyu Dai, Ping Chen +22
Blazars are active galactic nuclei with their relativistic jets pointing toward the observer, with two major sub-classes, the flat spectrum radio quasars and BL Lac objects. We pre…
The Gaia-ASAS-SN classical Cepheids sample: I. Sample Selection
L. Inno, H-W. Rix, K. Z. Stanek +4
We present a well-defined and characterized all-sky sample of classical Cepheids in the Milky Way, obtained by combining two time-domain all-sky surveys: Gaia DR2 (Gaia Collaborati…
The Milky Way Project: Probing Star Formation with First Results on Yellowballs from DR2
Grace Wolf-Chase, C. R. Kerton, Kathryn Devine +7
Yellowballs (YBs) were first discovered during the Milky Way Project citizen-science initiative (MWP; Simpson et al. 2012). MWP users noticed compact, yellow regions in Spitzer Spa…
A Unicorn in Monoceros: the dark companion to the bright, nearby red giant V723 Mon is a non-interacting, mass-gap black hole candidate
T. Jayasinghe, K. Z. Stanek, Todd A. Thompson +18
We report the discovery of the closest known black hole candidate as a binary companion to V723 Mon. V723 Mon is a nearby (), bright (~mag), evolved (…
