Eclipsing white dwarf from the Zwicky Transient Facility: II. Seven eclipsing double white dwarfs

J. van Roestel, K. Burdge, I. Caiazzo +15

In a systematic search for eclipsing white dwarfs using Zwicky transient facility (ZTF) data, we found seven eclipsing double white dwarfs with orbital periods ranging from 45 minu…

Precursor Activity Preceding Interacting Supernovae I: Bridging the Gap with SN 2022mop

S. J. Brennan, S. Barmentloo, S. Schulze +41

Over the past two decades, an increasing number of transients have shown luminous activity at their explosion sites weeks to years before an interacting supernova (SN) is observed.…

Variability of Central Stars of Planetary Nebulae with the Zwicky Transient Facility. I. Methods, Short-Timescale Variables, Binary Candidates, and the Unusual Nucleus of WeSb 1

Soumyadeep Bhattacharjee, S. R. Kulkarni, Albert K. H. Kong +16

Over the past several decades, time-series photometry of CSPNe has yielded significant results including, but not limited to, discoveries of nearly 100 binary systems, insights int…

Cyclotron emitting magnetic white dwarfs in post common envelope binaries discovered with the Zwicky Transient Facility

J. van Roestel, A. C. Rodriguez, P. Szkody +20

We present the discovery of 14 new (and recovery of 4 known) low accretion rate magnetic white dwarfs in post-common envelope binaries that emit strong cyclotron emission using the…

SN 2021adxl: A luminous nearby interacting supernova in an extremely low metallicity environment

S. J. Brennan, S. Schulze, R. Lunnan +17

SN 2021adxl is a slowly evolving, luminous, Type IIn supernova with asymmetric emission line profiles, similar to the well-studied SN 2010jl. We present extensive optical, near-ult…
