X-ray response to disk evolution in two gamma-Cas stars
Yael Naze, Gregor Rauw, Terrence Bohlsen +4
The Halpha emission of a set of southern gamma-Cas stars was monitored since 2019, with the aim of detecting transition events and examining how their peculiar X-ray emission would…
Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020
B. E. Morgado, B. Sicardy, F. Braga-Ribas +78
The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…
ASASSN-14ko is a Periodic Nuclear Transient in ESO 253-G003
Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle +24
We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated Survey for S…
The trans-Neptunian object (84922) 2003 VS2 through stellar occultations
Gustavo Benedetti-Rossi, P. Santos-Sanz, J. L. Ortiz +50
We present results from three world-wide campaigns that resulted in the detections of two single-chord and one multi-chord stellar occultations by the Plutino object (84922) 2003~V…
First stellar occultation by the Galilean moon Europa and upcoming events between 2019 and 2021
B. Morgado, G. Benedetti-Rossi, A. R. Gomes-Júnior +21
Context. Bright stellar positions are now known with an uncertainty below 1 mas thanks to Gaia DR2. Between 2019-2020, the Galactic plane will be the background of Jupiter. The den…
Discovery and Early Evolution of ASASSN-19bt, the First TDE Detected by TESS
Thomas W. -S. Holoien, Patrick J. Vallely, Katie Auchettl +22
We present the discovery and early evolution of ASASSN-19bt, a tidal disruption event (TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance of $d\…
