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…

Investigating the Nature of the Luminous Ambiguous Nuclear Transient ASASSN-17jz

Thomas W. -S. Holoien, Jack M. M. Neustadt, Patrick J. Vallely +31

We present observations of the extremely luminous but ambiguous nuclear transient (ANT) ASASSN-17jz, spanning roughly 1200 days of the object's evolution. ASASSN-17jz was discovere…

The 2019 outburst of the 2005 classical nova V1047 Cen: a record breaking dwarf nova outburst or a new phenomenon?

E. Aydi, K. V. Sokolovsky, J. S. Bright +28

We present a detailed study of the 2019 outburst of the cataclysmic variable V1047~Cen, which hosted a classical nova eruption in 2005. The peculiar outburst occurred 14 years afte…

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 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…

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 (…
