The long period radio transient ASKAP J1448-68 is a cataclysmic variable
Geoffrey Mo, Akash Anumarlapudi, Iris de Ruiter +8
Wide-field time-domain radio surveys have recently unveiled a new class of Galactic radio emitter: long period radio transients (LPTs). Despite the rapid pace of discovery, their o…
Beam monitoring for radiotherapy from conventional to FLASH dose rates using Low Gain Avalanche Silicon detectors
Cristhian Cadena, Antonio Cota Rodriguez, Tonatiuh García Chávez +10
We report the performance of low gain avalanche Silicon detectors (LGADs) for instantaneous electron and proton beam monitoring across dose rates ranging from conventional radiothe…
White dwarf + M dwarf Detached Binaries in Long Period Radio Transients: Observed Binary Parameters, Evolution, and Population Constraints
Antonio C. Rodriguez, Kareem El-Badry, Iris de Ruiter +4
Long period radio transients (LPTs) are the slowest radio-pulsing sources ever found, with the current population spanning periods of seven minutes to over six hours. Two of the th…
JWST observations of three long-period AM CVn binaries: detection of the donors and hints of magnetically truncated disks
Kareem El-Badry, Antonio C. Rodriguez, Matthew J. Green +1
We present JWST/NIRSpec high-cadence infrared spectroscopy of three long-period, eclipsing AM CVn binaries, Gaia14aae, SRGeJ0453, and ZTFJ1637. These systems have orbital periods o…
The White Dwarf Initial-Final Mass Relation from Open Clusters in Gaia DR3
David R. Miller, Ilaria Caiazzo, Jeremy Heyl +6
The initial-final mass relation (IFMR) links a star's birth mass to the mass of its white dwarf (WD) remnant, providing key constraints on stellar evolution. Open clusters offer th…
Circumstellar interaction in the extreme white dwarf merger remnant ZTF\,J1901+1458: A new class of white dwarf merger remnants with X-ray emission
Aayush Desai, Ilaria Caiazzo, Stephane Vennes +31
Double degenerate white dwarf (WD) mergers can exhibit extreme magnetic fields exceeding G and rapid rotation, but their spectral-energy distributions and high-energy emis…
Optical Spectroscopy of the Most Compact Accreting Binary Harboring a Magnetic White Dwarf and a Hydrogen-rich Donor
Ilkham Galiullin, Antonio C. Rodriguez, Kareem El-Badry +4
Accreting white dwarfs in close binary systems, commonly known as cataclysmic variables (CVs), with orbital periods below the canonical period minimum ( 80 minutes) are ra…
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…
Spectroscopic Detection of a 2.9-hour Orbit in a Long Period Radio Transient
Antonio C. Rodriguez
Long Period radio Transients (LPTs) are a mysterious new class of radio transients pulsating on periods of minutes to hours. So far, eight LPTs have been discovered predominantly a…
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…
