Hubble Space Telescope Imaging of Luminous Extragalactic Infrared Transients and Variables from the SPIRITS Survey
Howard E. Bond, Jacob E. Jencson, Patricia A. Whitelock +6
SPIRITS--the SPitzer InfraRed Intensive Transients Survey--searched for luminous infrared (IR) transients and variables in nearly 200 nearby galaxies from 2014 to 2019, using the w…
The search for failed supernovae with the Large Binocular Telescope: a new candidate and the failed SN fraction with 11 yr of data
J. M. M. Neustadt, C. S. Kochanek, K. Z. Stanek +5
We present updated results of the Large Binocular Telescope Search for Failed Supernovae. This search monitors luminous stars in 27 nearby galaxies with a current baseline of 11~yr…
Progenitor, Precursor and Evolution of the Dusty Remnant of the Stellar Merger M31-LRN-2015
Nadejda Blagorodnova, Viraj Karambelkar, Scott M. Adams +12
M31-2015-LRN is a likely stellar merger discovered in the Andromeda Galaxy in 2015. We present new optical to mid-infrared photometry and optical spectroscopy for this event. Archi…
Discovery of an intermediate-luminosity red transient in M51 and its likely dust-obscured, infrared-variable progenitor
Jacob E. Jencson, Scott M. Adams, Howard E. Bond +49
We present the discovery of an optical transient (OT) in Messier 51, designated M51 OT2019-1 (also ZTF19aadyppr, AT 2019abn, ATLAS19bzl), by the Zwicky Transient Facility (ZTF). Th…
SPIRITS Catalog of Infrared Variables: Identification of Extremely Luminous Long Period Variables
V. R. Karambelkar, S. M. Adams, P. A. Whitelock +11
We present a catalog of 417 luminous infrared variable stars with periods exceeding 250 days. These were identified in 20 nearby galaxies by the ongoing SPIRITS survey with the Spi…
Supernova Progenitors, Their Variability, and the Type IIP Supernova ASASSN-16fq in M66
C. S. Kochanek, M. Fraser, S. M. Adams +10
We identify a pre-explosion counterpart to the nearby Type IIP supernova ASASSN-16fq (SN 2016cok) in archival Hubble Space Telescope (HST) data. The source appears to be a blend of…
Discovery of Five Candidate Analogs for Carinae in Nearby Galaxies
Rubab Khan, Scott M. Adams, K. Z. Stanek +2
The late-stage evolution of very massive stars such as Carinae may be dominated by episodic mass ejections which may later lead to Type II superluminous supernova (SLSN-II; e.g…
LOSS's First Supernova? New Limits on the "Impostor" SN 1997bs
Scott M. Adams, C. S. Kochanek
We present new, late-time Hubble Space Telescope and Spitzer Space Telescope observations of the archetypal supernova (SN) impostor SN 1997bs. We show that SN 1997bs remains much f…
Stellar Mergers Are Common
C. S. Kochanek, Scott M. Adams, Krzysztof Belczynski
The observed Galactic rate of stellar mergers or the initiation of common envelope phases brighter than M_V=-3 (M_I=-4) is of order 0.5 (0.3)/year with 90% confidence statistical u…
Modeling the System Parameters of 2M1533+3759: A New Longer-Period Low-Mass Eclipsing sdB+dM Binary
B. -Q. For, E. M. Green, G. Fontaine +17
We present new photometric and spectroscopic observations for 2M 1533+3759 (= NSVS 07826147). It has an orbital period of 0.16177042 day, significantly longer than the 2.3--3.0 hou…
