SHORTEST RECURRENCE PERIODS OF FORCED NOVAE [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT We revisit hydrogen shell burning on white dwarfs (WDs) with higher mass accretion rates than the stability limit, , above which hydrogen burning is stable. Novae occur with mass accretion rates below the limit. For an accretion rate >

A Self-consistent Model for a Full Cycle of Recurrent Novae—Wind Mass-loss Rate and X-Ray Luminosity [PDF]

open access: yes, 2017
An unexpectedly slow evolution in the pre-optical-maximum phase was suggested in the very short recurrence period of nova M31N 2008-12a. To obtain reasonable nova light curves we have improved our calculation method by consistently combining optically ...

Lepto-hadronic Interpretation of 2021 RS Ophiuchi Nova Outburst

open access: yesThe Astrophysical Journal, 2023
Very-high-energy (VHE; 100 GeV < E ≤ 100 TeV) and high-energy (HE; 100 MeV < E ≤ 100 GeV) gamma rays were observed from the symbiotic recurrent nova RS Ophiuchi (RS Oph) during its outburst in 2021 August by various observatories, such as the High Energy

Search for soft X-ray flashes at the fireball phase of classical/recurrent novae using MAXI/GSC data [PDF]

open access: yes, 2016
We searched for precursive soft X-ray flashes (SXFs) associated with optically-discovered classical or recurrent novae in the data of five-years all-sky observations with Gas Slit Camera (GSC) of the Monitor of All-sky X-ray Image (MAXI).

DUAL MOBILITY CUP CEMENTED INTO POROUS TRABECULAR METAL SHELL DURING REVISION TOTAL HIP ARTHROPLASTY [PDF]

open access: yesJournal of IMAB, 2023
Revision total hip arthroplasty (RTHA) is a challenging procedure when we speak about acetabular defects and recurrent instability. There are multiple reasons like the number of previous revisions, implant position, bone quality, patient characteristics ...

X-RAY FLASHES IN RECURRENT NOVAE: M31N 2008-12a AND THE IMPLICATIONS OF THE SWIFT NONDETECTION [PDF]

open access: yes, 2016
Models of nova outbursts suggest that an X-ray flash should occur just after hydrogen ignition. However, this X-ray flash has never been observationally confirmed.

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova

open access: yesThe Astrophysical Journal Letters, 2023
T CrB is a symbiotic recurrent nova that exhibits quiescent and active phases between its classical nova eruptions. The statistical properties of these active phases have been poorly studied thus far. Because of that their nature remained unknown.

The slow decline of the Galactic recurrent novae T Pyxidis, IM Normae, and CI Aquilae [PDF]

open access: yes, 2015
A distinguishing trait of the three known Galactic recurrent novae with the shortest orbital periods, T Pyx, IM Nor, and CI Aql, is that their optical decline time-scales are significantly longer than those of the other recurrent systems.

Bipolar recurrent nova outbursts - I. Hydrodynamic models [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1993
We describe hydrodynamic models of bipolar outbursts in recurrent nova systems containing a red giant with a dense wind. Two mechanisms are investigated for the production of the bipolarity observed in the outbursts of some such systems - a model in which the outburst occurs as a point explosion in an anisotropic wind, and one in which the wind is ...

CIRCUMSTELLAR SHELL FORMATION IN SYMBIOTIC RECURRENT NOVAE [PDF]

open access: yesThe Astrophysical Journal, 2012
We present models of spherically symmetric recurrent nova shells interacting with circumstellar material in a symbiotic system composed of a red giant expelling a wind, and a white dwarf accreting from this material. Recurrent nova eruptions periodically eject material at high velocities ($\gtrsim 10^3$ km/s) into the red giant wind profile, creating a
