Dramatic rebrightening of the type-changing stripped-envelope supernova SN 2023aew

Yashvi Sharma, Jesper Sollerman, Shrinivas R. Kulkarni +32

Multi-peaked supernovae with precursors, dramatic light-curve rebrightenings, and spectral transformation are rare, but are being discovered in increasing numbers by modern night-s…

Minutes-duration Optical Flares with Supernova Luminosities

Anna Y. Q. Ho, Daniel A. Perley, Ping Chen +74

In recent years, certain luminous extragalactic optical transients have been observed to last only a few days. Their short observed duration implies a different powering mechanism…

Photometric prioritization of neutron star merger candidates

E. O. Ofek, N L. Strotjohann, I. Arcavi +12

Rapid identification of the optical counterparts of Neutron Star (NS) merger events discovered by gravitational wave detectors may require observing a large error region and siftin…

A 12.4 day periodicity in a close binary system after a supernova

Ping Chen, Avishay Gal-Yam, Jesper Sollerman +37

Neutron stars and stellar-mass black holes are the remnants of massive star explosions. Most massive stars reside in close binary systems, and the interplay between the companion s…

Supernovae 2016bdu and 2005gl, and their link with SN 2009ip-like transients: another piece of the puzzle

A. Pastorello, C. S. Kochanek, M. Fraser +52

Supernova (SN) 2016bdu is an unusual transient resembling SN 2009ip. SN 2009ip-like events are characterized by a long-lasting phase of erratic variability which ends with two lumi…

Fourteen new eclipsing white dwarf plus main-sequence binaries from the SDSS and Catalina surveys

S. G. Parsons, C. Agurto-Gangas, B. T. Gaensicke +13

We report on the search for new eclipsing white dwarf plus main-sequence (WDMS) binaries in the light curves of the Catalina surveys. We use a colour selected list of almost 2000 c…

Detection of an outburst one year prior to the explosion of SN 2011ht

M. Fraser, M. Magee, R. Kotak +18

Using imaging from the Pan-STARRS1 survey, we identify a precursor outburst at epochs 287 and 170 days prior to the reported explosion of the purported Type IIn supernova (SN) 2011…

Probing the Outer Galactic halo with RR Lyrae from the Catalina Surveys

A. J. Drake, M. Catelan, S. G. Djorgovski +10

We present the analysis of 12227 type-ab RR Lyrae found among the 200 million public lightcurves in the Catalina Surveys Data Release 1 (CSDR1). These stars span the largest volume…

The Rise of the Remarkable Type IIn Supernova SN 2009ip

J. L. Prieto, J. Brimacombe, A. J. Drake +1

Recent observations by Mauerhan et al. have shown the unprecedented transition of the previously identified luminous blue variable (and supernova impostor) SN 2009ip to a real Type…

The evolutionary state of short period magnetic white dwarf binaries

E. Breedt, B. T. Gaensicke, J. Girven +4

We present phase-resolved spectroscopy of two new short period low accretion rate magnetic binaries, SDSSJ125044.42+154957.3 (Porb = 86 min) and SDSSJ151415.65+074446.5 (Porb = 89…

New Cataclysmic Variable 1RXS J073346.0+261933 in Gemini

D. V. Denisenko, A. J. Drake, S. G. Djorgovski +3

In course of the search for the optical identifications associated with ROSAT X-ray sources we have found a highly variable object with the very unusual long-term behavior, color i…

A deeply eclipsing detached double helium white dwarf binary

S. G. Parsons, T. R. Marsh, B. T. Gänsicke +2

Using Liverpool Telescope+RISE photometry we identify the 2.78 hour period binary star CSS 41177 as a detached eclipsing double white dwarf binary with a 21,100K primary star and a…

Spectral and Photometric Monitoring of Distant Core-Collapse Supernovae in the SAO RAS

A. S. Moskvitin, T. A. Fatkhullin, V. V. Sokolov +4

This paper describes the aims, objectives and first results of the observational program for the study of distant core-collapse supernovae (SNe) with redshifts z < 0.3. This work i…

SDWFS-MT-1: A Self-Obscured Luminous Supernova at z~0.2

Szymon Kozlowski, C. S. Kochanek, D. Stern +22

We report the discovery of a six-month-long mid-infrared transient, SDWFS-MT-1 (aka SN 2007va), in the Spitzer Deep, Wide-Field Survey of the NOAO Deep Wide-Field Survey Bootes fie…
