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…
Spectroscopic distance, mass, and age estimations for APOGEE DR17
Alexander Stone-Martinez, Jon A. Holtzman, Julie Imig +3
We derive distances and masses of stars from the Sloan Digital Sky Survey (SDSS) Apache Point Observatory Galactic Evolution Experiment (APOGEE) Data Release 17 (DR17) using simple…
Optical Time-Series Photometry of the Symbiotic Nova V1835 Aquilae
Robert V. Caddy, Andrew C. Layden, Daniel E. Reichart +7
We present time-series CCD photometry in the passbands of the recently identified symbiotic nova V1835 Aquilae (NSV 11749) over an interval of 5.1 years with 7-14 day cadenc…
Panchromatic evolution of three luminous red novae: Forbidden hugs in pandemic times -- IV
A. Pastorello, G. Valerin, M. Fraser +77
We present photometric and spectroscopic data on three extragalactic luminous red novae (LRNe): AT2018bwo, AT2021afy, and AT2021blu. AT2018bwo was discovered in NGC45 (at 6.8 Mpc)…
The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
Constraining the Evolution of Cataclysmic Variables via the Masses and Accretion Rates of their Underlying White Dwarfs
A. F. Pala, B. T. Gänsicke, D. Belloni +28
We report on the masses (), effective temperatures () and secular mean accretion rates () of 43 cataclysmic variable (CV) wh…
AT 2019qyl in NGC 300: Internal Collisions in the Early Outflow from a Very Fast Nova in a Symbiotic Binary
Jacob E. Jencson, Jennifer E. Andrews, Howard E. Bond +39
Nova eruptions, thermonuclear explosions on the surfaces of white dwarfs (WDs), are now recognized to be among the most common shock-powered astrophysical transients. We present th…
Full orbital solution for the binary system in the northern Galactic disc microlensing event Gaia16aye
Łukasz Wyrzykowski, P. Mróz, K. A. Rybicki +182
Gaia16aye was a binary microlensing event discovered in the direction towards the northern Galactic disc and was one of the first microlensing events detected and alerted to by the…
YZ Phe: an active contact binary with variation of the O'Connell effect and orbital period change
T. Sarotsakulchai, S. -B. Qian, B. Soonthornthum +7
YZ Phe is a very short-period contact binary (Sp.= ) with an orbital period of 0.2347 days near the short period limit (0.22 d). We present the complete light curves in $VRI…
TY Pup: a low-mass-ratio and deep contact binary as a progenitor candidate of luminous red novae
T. Sarotsakulchai, S. B. Qian, B. Soonthornthum +6
TY Pup is a well-known bright eclipsing binary in southern hemisphere with an orbital period of 0.8192 days. New light curves in bands were obtained with the 0.61-m…
Signatures of an eruptive phase before the explosion of the peculiar core-collapse SN 2013gc
Andrea Reguitti, Andrea Pastorello, Giuliano Pignata +12
We present photometric and spectroscopic analysis of the peculiar core-collapse SN 2013gc, spanning seven years of observations. The light curve shows an early maximum followed by…
