We present a quintuple star system that contains two eclipsing binaries. The unusual architecture includes two stellar images separated by 11" on the sky: EPIC 212651213 and EPIC 2…
The Continuing Story of SN IIb 2013df: New Optical and IR Observations and Analysis
Tamás Szalai, József Vinkó, Andrea P. Nagy +17
SN 2013df is a nearby Type IIb supernova that seems to be the spectroscopic twin of the well-known SN 1993J. Previous studies revealed many, but not all interesting properties of t…
