Constraints on relic magnetic black holes by Melissa D. Diamond, David E. Kaplan

“…The dominant constraints come from white dwarf destruction for low and intermediate masses (2 × 10 −5 g – 4 × 1012 g) and Galactic gas cloud heating for heavier masses (> 4 × 1012 g). …”

Wind Roche-Lobe overflow: a new mass-transfer mode for wide binaries by Mohamed, S, Podsiadlowski, P

“…Most symbiotic binaries consist of an evolved giant star and a hot, accreting companion, typically a white dwarf. In wide symbiotic binaries, the companion may accrete part of the wind emitted by the giant by Bondi-Hoyle accretion. …”

The progenitors of type Ia supernovae by Tout, C, Regos, E, Wickramasinghe, D, Hurley, JR, Pols, O

“…We consider exploding Chandrasekhar-mass CO white dwarfs and sub-Chandrasekhar edge lit detonations to be the most viable candidates. …”

A single-degenerate model for the progenitor of the Type Ia supernova 2002ic by Han, Z, Podsiadlowski, P

The formation of subdwarf B stars by Han, Z, Podsiadlowski, P, Maxted, P, Marsh, T, Ivanova, N

“…We performed full binary evolution calculations and carried out binary population synthesis studies in order to investigate the formation of subdwarf B (sdB) stars via, the channels of stable Roche lobe overflow (RLOF), common envelope ejection and helium white dwarf mergers. Our model is successful in the explanation of observational properties of sdB stars, e.g. we explained the orbital period - minimum companion mass (log P - M-comp) diagram, the effective temperature - surface gravity (T-eff - log g) diagram, the orbital period distribution, the log(gtheta(4)) (theta = 5040/T-eff) distribution, the mass function distribution, the binary. fraction of sdB stars, the fraction of sdB binaries with WD companions, the birth rates, the space number densities, etc. …”

Cataclysmic Variables as Supernova Ia Progenitors by Stella Kafka

“…Although the identification of the progenitors of type Ia supernovae (SNeIa) remains controversial, it is generally accepted that they originate from binary star systems in which at least one component is a carbon-oxygen white dwarf (WD); those systems are grouped under the wide umbrella of cataclysmic variables. …”

Light-Time Effect and Mass Transfer in the Triple Star SW Lyncis by Chun-Hwey Kim

“…The third-body with a minimum mass of 1.13M may be a binary or a white dwarf. The rate of secular period-decrease were obtained as ¡âP/P = -12.45 x 10^-11, implying the mass-transfer from the massive primary star to the secondary. …”

GRB 211211A-like Events and How Gravitational Waves May Tell Their Origins by Yi-Han Iris Yin, Bin-Bin Zhang, Hui Sun, Jun Yang, Yacheng Kang, Lijing Shao, Yu-Han Yang, Bing Zhang

“…On the other hand, a neutron star–white dwarf binary would also produce a considerable S/N during the inspiral phase at decihertz and is detectable by next-generation spaceborne detectors DECIGO and the Big Bang Observer. …”

On the nature of Tycho Brahe’s supernova by Pilar Ruiz–Lapuente, Pilar Ruiz–Lapuente

“…The abundance studies from X–ray spectroscopy of the whole remnant point to a nuclear burning of the kind of a delayed detonation explosion of a Chandrasekhar–mass white dwarf. A tentative single degenerate path to explosion was suggested from the exploration of the stars in the field of SN 1572. …”

Discussions on the Nature of GLEAM-X J162759.5–523504.3 by H. Tong

“…We try to understand both its radio emission and pulsation in the neutron star scenario as an alternative to the white dwarf model. We think that (1) from the radio emission point of view, GLEAM-X J1627 can be a radio-loud magnetar; (2) from the rotational evolution point of view, GLEAM-X J1627 is unlikely to be an isolated magnetar; (3) the 1091 s period is unlikely to be the precession period; (4) GLEAM-X J1627 may be a radio-loud magnetar spun down by a fallback disk; (5) the pulsar death line is modified due to the presence of a fallback disk or a twisted magnetic field. …”

A Multiwavelength Light-curve Analysis of the Classical Nova YZ Ret: An Extension of the Universal Decline Law to the Nebular Phase by Izumi Hachisu, Mariko Kato

“…We propose a comprehensive model that explains the observational properties. The white dwarf mass is determined to be ∼1.33 M _☉ , which reproduces the multiwavelength light curves of YZ Ret, from optical, X-ray, to gamma-ray. …”

On the formation of single and binary helium-rich sdO stars by Justham, S, Podsiadlowski, P, Han, Z

“…We propose a formation channel for the previously unexplained helium-rich subdwarf O (He-rich sdO) stars in which post-subdwarf B (sdB) stars (i.e. hybrid COHe white dwarfs) reignite helium burning in a shell after gaining matter from their helium white-dwarf (WD) companions. …”

Type IIn supernovae at redshift z approximately 2 from archival data. by Cooke, J, Sullivan, M, Barton, E, Bullock, J, Carlberg, R, Gal-Yam, A, Tollerud, E

“…Supernovae have been confirmed to redshift z approximately 1.7 (refs 1, 2) for type Ia (thermonuclear detonation of a white dwarf) and to z approximately 0.7 (refs 1, 3-5) for type II (collapse of the core of the star). …”

“…A comparison of the accretion rate with different models on the MWD–Ṁ plane yields the mass of a CO white dwarf, powering the H-shell flashes every ∼1 yr, to be >1.36 M ⊙ and growing with time, making M31N 2008-12a a strong candidate for the single degenerate scenario of the Type Ia supernovae progenitor.…”
