Physical Properties of the Host Galaxies of Ca-rich Transients

Y. Dong, D. Milisavljevic, J. Leja +8

Calcium-rich (Ca-rich) transients are a new class of supernovae (SNe) that are known for their comparatively rapid evolution, modest peak luminosities, and strong nebular calcium e…

Constraints on the Sub-pc Environment of the Nearby Type Iax SN 2014dt from Deep X-ray and Radio Observations

Candice M. Stauffer, Raffaella Margutti, Justin D. Linford +8

We present X-ray and radio observations of what may be the closest type Iax supernova (SN) to date, SN 2014dt (d=12.3-19.3 Mpc) and provide tight constraints on the radio and X-ray…

A Cool and Inflated Progenitor Candidate for the Type Ib Supernova 2019yvr at 2.6 Years Before Explosion

Charles D. Kilpatrick, Maria R. Drout, Katie Auchettl +13

We present Hubble Space Telescope imaging of a pre-explosion counterpart to SN 2019yvr obtained 2.6 years before its explosion as a type Ib supernova (SN Ib). Aligning to a post-ex…

Late-time Observations of Calcium-Rich Transient SN 2019ehk Reveal a Pure Radioactive Decay Power Source

Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +11

We present imaging of the Calcium-rich supernova (SN) 2019ehk at 276 - 389 days after explosion. These observations represent the latest photometr…

SN 2019ehk: A Double-Peaked Ca-rich Transient with Luminous X-ray Emission and Shock-Ionized Spectral Features

Wynn V. Jacobson-Galán, Raffaella Margutti, Charles D. Kilpatrick +64

We present panchromatic observations and modeling of the Calcium-rich supernova 2019ehk in the star-forming galaxy M100 (d16.2 Mpc) starting 10 hours after explosion and c…

Ca hnk: Calcium-rich Transient SN 2016hnk from the Helium Shell Detonation of a Sub-Chandrasekhar White Dwarf

Wynn V. Jacobson-Galán, Abigail Polin, Ryan J. Foley +11

We present observations and modeling of SN 2016hnk, a Ca-rich supernova (SN) that is consistent with being the result of a He-shell double-detonation explosion of a C/O white dwarf…
