Spitzer + VLTI-GRAVITY Measure the Lens Mass of a Nearby Microlensing Event
Weicheng Zang, Subo Dong, Andrew Gould +24
We report the lens mass and distance measurements of the nearby microlensing event TCP J05074264+2447555. We measure the microlens parallax vector using Spitzer and gro…
Luminous Red Novae: Stellar Mergers or Giant Eruptions?
A. Pastorello, E. Mason, S. Taubenberger +36
We present extensive datasets for a class of intermediate-luminosity optical transients known as "luminous red novae" (LRNe). They show double-peaked light curves, with an initial…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
Discovery and Early Evolution of ASASSN-19bt, the First TDE Detected by TESS
Thomas W. -S. Holoien, Patrick J. Vallely, Katie Auchettl +22
We present the discovery and early evolution of ASASSN-19bt, a tidal disruption event (TDE) discovered by the All-Sky Automated Survey for Supernovae (ASAS-SN) at a distance of $d\…
ASASSN-18tb: A Most Unusual Type Ia Supernova Observed by TESS and SALT
P. J. Vallely, M. Fausnaugh, S. W. Jha +16
We present photometric and spectroscopic observations of the unusual Type Ia supernova ASASSN-18tb, including a series of SALT spectra obtained over the course of nearly six months…
The Extraplanar Type II Supernova ASASSN-14jb in the Nearby Edge-on Galaxy ESO 467-G051
Nicolas Meza, J. L. Prieto, A. Clocchiatti +10
We present optical photometry and spectroscopy of the Type II supernova ASASSN-14jb, together with VLT MUSE IFU observations of its host galaxy and a nebular-phase spectrum. This S…
