A long-duration superflare on the K giant HD 251108

Hans Moritz Günther, Dheeraj Pasham, Alexander Binks +10

Many giant stars are magnetically active, which causes rotational variability, chromospheric emission lines, and X-ray emission. Large outbursts in these emission features can set…

MASTER OT J030227.28+191754.5: an unprecedentedly energetic dwarf nova outburst

Yusuke Tampo, Taichi Kato, Keisuke Isogai +60

We present a detailed study of the MASTER OT J030227.28+191754.5 outburst in 2021-2022, reaching an amplitude of 10.2 mag and a duration of 60 d. The detections of (1) the double-p…

Accretion Funnel Reconfiguration during an Outburst in a Young Stellar Object: EX Lupi

Koshvendra Singh, Joe P. Ninan, Marina M. Romanova +14

EX Lupi, a low-mass young stellar object, went into an accretion-driven outburst in March of 2022. The outburst caused a sudden phase change of ~ 112 5 in…

Optical and soft X-ray light-curve analysis during the 2022 eruption of U Scorpii: structural changes in the accretion disk

Katsuki Muraoka, Naoto Kojiguchi, Junpei Ito +52

We present our optical photometric observations of the 2022 eruption of the recurrent nova U Scorpii (U Sco) using 49,152 data points over 70 d following the optical peak. We have…

A survey for variable young stars with small telescopes: VIII -- Properties of 1687 Gaia selected members in 21 nearby clusters

Dirk Froebrich, Aleks Scholz, Justyn Campbell-White +60

The Hunting Outbursting Young Stars (HOYS) project performs long-term, optical, multi-filter, high cadence monitoring of 25 nearby young clusters and star forming regions. Utilisin…
