Long-term optical and near-infrared photometric evolution of SN 2019vxm, an interacting Type IIn supernova
Klára Lelkes, László Molnár, József Vinkó +12
The diversity of Type IIn supernovae is largely driven by the properties of the circumstellar material (CSM) they explode into. We examine the temporal evolution of SN 2019vxm, an…

SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…

Asteroseismic mass and radius of the naked-eye red giant HD145250
László Molnár, Klára Lelkes
We present the first asteroseismic analysis of the bright, nearby red giant star, HD145250. We calculate the global seismic quantities of the star from single-sector, 2-minute TESS…
