On the observability of recurrent nova super-remnants
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACTThe nova super-remnant (NSR) surrounding M 31N 2008-12a (12a), the annually erupting recurrent nova (RN), is the only known example of this phenomenon. As this structure has grown as a result of frequent eruptions from 12a, we might expect to see NSRs around other RNe; this would confirm the RN–NSR association and strengthen the connection ...

SHORTEST RECURRENCE PERIODS OF FORCED NOVAE [PDF]
The 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 >

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

A spectroscopic survey of recurrent novae at minimum [PDF]
International Astronomical Union Colloquium, 1990 From 1986 to 1988 optical spectroscopy near minimum of all then established recurrent novae (excluding recurrent X-ray novae such as V616 Mon and V404 Cyg) was carried out with the 3.6 m and 1.5 m telescopes of ESO, using EFOSC with CCD and the Cassegrain spectrograph with CCD or IDS, respectively.

Symbiotic Star T CrB as an Extreme SU UMa–type Dwarf Nova
The 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 1987 outburst of the recurrent nova U Sco [PDF]
Monthly Notices of the Royal Astronomical Society, 1988 AbstractSpectral observations obtained soon after the 1987 brightening of U Sco support a thermonuclear runaway model for outbursts of this object. Spectra later in the decline are, however, more characteristic of a hot accretion disc. These observations are reconciled in a model where the low-mass high-velocity shell ejected from the surface of the ...

Snowflakes in a Furnace: Formation of CO and Dust in a Recurrent Nova Eruption
The Astrophysical Journal Letters, 2023 We report the detection of carbon monoxide (CO) and dust, formed under hostile conditions, in recurrent nova V745 Sco about 8.7 days after its 2014 outburst. The formation of molecules or dust has not been recorded previously in the ejecta of a recurrent

V2487 Oph 1998: a post nova in an intermediate polar
EPJ Web of Conferences, 2014 V2487 Oph (Nova Oph 1998) is a classical nova that exploded in 1998. XMM-Newton observations performed between 2 and 9 years after the explosion showed emission related to restablished accretion, and indicative of a magnetic white dwarf.

Arthritis Care &Research, EarlyView.Objective We aimed to construct and evaluate the first laboratory‐based frailty index (FI‐Lab) for predicting adverse outcomes in systemic lupus erythematosus (SLE) and to compare its predictive ability to that of an existing clinical FI. Methods We used data from a single‐center prospective cohort of adult patients with SLE whose baseline visit ...
