We present panchromatic observations and modeling of the Calcium-rich supernova (SN)
2019ehk in the star-forming galaxy M100 (d≈ 16.2 Mpc) starting 10 hr after explosion and
continuing for∼ 300 days. SN 2019ehk shows a double-peaked optical light curve peaking
at t= 3 and 15 days. The first peak is coincident with luminous, rapidly decaying Swift-XRT–
discovered X-ray emission (${L} _ {{\rm {x}}}\approx {10}^{41}\,\mathrm {erg}\,{{\rm {s}}}^{-1} $

Abstract
We present panchromatic observations and modeling of the Calcium-rich supernova (SN) 2019ehk in the star-forming galaxy M100 (d≈ 16.2 Mpc) starting 10 hr after explosion and continuing for∼ 300 days. SN 2019ehk shows a double-peaked optical light curve peaking at t= 3 and 15 days. The first peak is coincident with luminous, rapidly decaying Swift-XRT–discovered X-ray emission (
