A Package for the Automated Classification of Images Containing Supernova Light Echoes

A. Bhullar, R. A. Ali, D. L. Welch

Context. The so-called "light echoes" of supernovae - the apparent motion of outburst-illuminated interstellar dust - can be detected in astronomical difference images; however, li…

Mass Measurements of Neutron-Rich Gallium Isotopes Refine Production of Nuclei of the First r-Process Abundance Peak in Neutron Star Merger Calculations

M. P. Reiter, S. Ayet San Andrés, S. Nikas +33

We report mass measurements of neutron-rich Ga isotopes Ga with TRIUMF's Ion Trap for Atomic and Nuclear science (TITAN). The measurements determine the masses of $^{80-8…

A plethora of new R Coronae Borealis stars discovered from a dedicated spectroscopic follow-up survey

P. Tisserand, G. C. Clayton, M. S. Bessell +7

It is increasingly suspected that the rare R Coronae Borealis (RCB) stars - hydrogen-deficient and carbon-rich supergiant stars - are the products of mergers of CO/He white-dwarf b…

Tracking down R Coronae Borealis stars using the WISE All-Sky survey

P. Tisserand, G. C. Clayton, D. L. Welch

R Coronae Borealis stars (RCBs) are the best candidates to be the products of white dwarf mergers in the intermediate mass range ( M). After a merger, a…

A Hubble Space Telescope Survey for Novae in M87. II. Snuffing out the Maximum Magnitude - Rate of Decline Relation for Novae as a Non-Standard Candle, and a Prediction of the Existence of Ultrafast Novae

Michael M. Shara, Trisha Doyle, Tod R. Lauer +9

The extensive grid of numerical simulations of nova eruptions of Yaron et al.(2005) first predicted that some classical novae might deviate significantly from the Maximum Magnitude…

A Hubble Space Telescope survey for novae in M87. III. Are novae good standard candles 15 days after maximum brightness?

Michael M. Shara, Trisha F. Doyle, Ashley Pagnotta +13

Ten weeks of daily imaging of the giant elliptical galaxy M87 with the Hubble Space Telescope (HST) has yielded 41 nova light curves of unprecedented quality for extragalactic cata…
