New Pulse Timing Measurements of the sdBV Star CS 1246
Zackary L. Hutchens, Brad N. Barlow, Alan Vasquez Soto +5
CS 1246 is a hot subdwarf B star discovered in 2009 to exhibit a single, large-amplitude radial pulsation. An O-C diagram constructed from this mode revealed reflex motion due to t…
The early detection and follow-up of the highly obscured Type II supernova 2016ija/DLT16am
L. Tartaglia, D. J. Sand, S. Valenti +45
We present our analysis of the Type II supernova DLT16am (SN~2016ija). The object was discovered during the ongoing (DLT40) one day cadence supernova search a…
2FGL J0846.0+2820: A new neutron star binary with a giant secondary and variable -ray emission
Samuel J. Swihart, Jay Strader, Tyrel J. Johnson +11
We present optical photometric and spectroscopic observations of the likely stellar counterpart to the unassociated \emph{Fermi}-Large Area Telescope (LAT) -ray source 2FGL J084…
The discovery of the electromagnetic counterpart of GW170817: kilonova AT 2017gfo/DLT17ck
Stefano Valenti, David J. Sand, Sheng Yang +7
During the second observing run of the Laser Interferometer gravitational- wave Observatory (LIGO) and Virgo Interferometer, a gravitational-wave signal consistent with a binary ne…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
An empirical limit on the kilonova rate from the DLT40 one day cadence Supernova Survey
Sheng Yang, Stefano Valenti, Enrico Cappellaro +6
Binary neutron star mergers are important to understand stellar evolution, the chemical enrichment of the universe via the r-process, the physics of short gamma-ray bursts, gravita…
