Detached Post-Algol Eclipsing Binaries Caught Between Case A and Case AB Mass Transfer
Megan G. Frank, Maxwell Moe, Nathan Smith
For sixty years, stellar evolutionary models have predicted that intermediate-mass stars slightly contract on the terminal-age main-sequence (TAMS) as they exhaust hydrogen in thei…

Evidence for Extended Hydrogen-Poor CSM in the Three-Peaked Light Curve of Stripped Envelope Ib Supernova
Yossef Zenati, Qinan Wang, Alexey Bobrick +40
We present multi-band ATLAS photometry for SN 2019tsf, a stripped-envelope Type Ib supernova (SESN). The SN shows a triple-peaked light curve and a late (re-)brightening, making it…

The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission
Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40
SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
