Transiting Planetary Debris near the Roche Limit of a White Dwarf on a 4.97hr Orbit -- and its Vanishing
Joseph A. Guidry, Zachary P. Vanderbosch, J. J. Hermes +9
We present the discovery of deep, irregular, periodic transits towards the white dwarf ZTFJ19444557 using follow-up time-series photometry and spectroscopy from Palomar, Kec…
Probing the Neutral Fraction of the Warm Ionized Medium via [NI] 5200
S. R. Kulkarni, S. Noll, W. Kausch +1
Most of the ionized mass in the Milky Way is in the Warm Ionized Medium (WIM) and not in the bright H~II regions. The WIM is traced by dispersion measure and has been extensively s…
Thick Disks around White Dwarfs viewed 'Edge-off': Effects on Transit Properties and Infrared Excess
Soumyadeep Bhattacharjee
A significant fraction of white dwarfs (WDs) host dust/debris disks formed from the tidal disruption of asteroids and planetesimals. Several studies indicate that the disks can att…
Variability of Central Stars of Planetary Nebulae with the Zwicky Transient Facility. II. Long-Timescale Variables including Wide Binary and Late Thermal Pulse Candidates
Soumyadeep Bhattacharjee, Nicole Reindl, Howard E. Bond +14
In this second paper on our variability survey of central stars of planetary nebulae (CSPNe) using ZTF, we report 11 long-timescale variables with variability timescales ranging fr…
A ZTF Search for Circumstellar Debris Transits in White Dwarfs: Six New Candidates, one with Gas Disk Emission, identified in a Novel Metric Space
Soumyadeep Bhattacharjee, Zachary P. Vanderbosch, Mark A. Hollands +13
White dwarfs (WDs) showing transits from orbiting planetary debris provide significant insights into the structure and dynamics of debris disks. This is a rare class of objects wit…
Prospects for Systematic Planetary Nebulae Detection with the Census of the Local Universe Narrowband Survey
Rong Du, David O. Cook, Soumyadeep Bhattacharjee +8
We investigate the efficacy of a systematic planetary nebula (PN) search in the Census of the Local Universe (CLU) narrowband (H) survey that covers a considerably larger sky re…
