The Early Ultraviolet Light Curves of Type II Supernovae and the Radii of Their Progenitor Stars

The Early Ultraviolet Light Curves of Type II Supernovae and the Radii of Their Progenitor Stars

We present a sample of 34 normal Type II supernovae (SNe II) detected with the Zwicky Transient Facility, with multiband UV light curves starting at t ≤ 4 days after explosion, and X-ray observations. We characterize the early UV-optical color, provide empirical host-extinction corrections, and show...
