Bernhard-1: An Eccentric Binary Periodically Obscured by its Misaligned Circumbinary Disk
Zhecheng Hu, Wei Zhu, Ping Chen +2
Bernhard-1 is a proposed KH 15D-like circumbinary disk occultation (CBO) system, but its binary nature and disk geometry have not previously been confirmed. We present new optical…

Expanding the parameter space of 2002es-like type Ia supernovae: on the underluminous ASASSN-20jq / SN 2020qxp
Subhash Bose, Maximilian D. Stritzinger, Chris Ashall +23
We present optical photometric and spectroscopic observations of the peculiar Type Ia supernova ASASSN-20jq/SN 2020qxp. It is a low-luminosity object with a peak absolute magnitude…

An Eccentric Binary with a Misaligned Circumbinary Disk
Zhecheng Hu, Wei Zhu, Fei Dai +4
We present spectroscopic and photometric observations of Bernhard-2, which was previously identified as a candidate system to host a misaligned circumbinary disk. Our spectroscopic…
