The Astrophysical Journal Supplement Series, 2023 M87 has been monitored with a cadence of 5 days over a span of 9 months through the near-ultraviolet (NUV; F275W) and optical (F606W) filters of the Wide Field Camera 3 (WFC3) of the Hubble Space Telescope.

Discovery of a new photometric sub-class of faint and fast classical novae [PDF]
, 2010 We present photometric and spectroscopic follow-up of a sample of extragalactic novae discovered by the Palomar 60-inch telescope during a search for "Fast Transients In Nearest Galaxies" (P60-FasTING). Designed as a fast cadence (1-day) and deep (g < 21

Carbon–Oxygen Classical Novae Are Galactic 7Li Producers as well as Potential Supernova Ia Progenitors [PDF]
Astrophysical Journal, 2019 We report on studies of classical nova (CN) explosions where we follow the evolution of thermonuclear runaways (TNRs) on carbon–oxygen (CO) white dwarfs (WDs).

Relation between Long-term Activity and Luminosity of the Pre- and Post-novae CT Ser and V446 Her
The Astronomical Journal, 2023 We show a relation of the pre- and post-nova activity of CT Ser (nova 1948) and V446 Her (nova 1960), known to have remarkably similar orbital periods P _orb . We use both photographic and CCD photometric observations.

The UBV Color Evolution of Classical Novae. IV. Time-stretched (U − B)0–(M B − 2.5 log f s) and (V − I)0–(M I − 2.5 log f s) Color–Magnitude Diagrams of Novae in Outbursts [PDF]
, 2020 Light curves and color evolutions of two classical novae can be largely overlapped if we properly squeeze or stretch the timescale of a target nova against that of a template nova by .

Theory of Classical Novae [PDF]
Proceedings of The Golden Age of Cataclysmic Variables and Related Objects - III — PoS(Golden2015), 2017 We briefly review the current understanding of classical novae. Nova light curves basically exhibit a homologous nature, beside the dust blackout and oscillatory behavior, in spite of very different evolution timescale from fast to slow novae. Optically thick winds governs the evolution of decay phase of nova outbursts, of which mass-loss rate ...

Classical novae: Properties between outbursts [PDF]
International Astronomical Union Colloquium, 1990 With the recent publication of Classical Novae, edited by Bode and Evans, there is no need for me to give a list of novae or their overall characteristics. Furthermore, probably the most interesting developments in the past few years in studies of novae during quiescence have been in those areas (magnetic systems, long term brightness variations) which

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 ROSAT observations of classical novae [PDF]
International Astronomical Union Colloquium, 1996 We observed a number of classical and recurrent novae in the Galaxy and the LMC with the ROSAT X-ray telescope and searched the archival data for other serendipitous observations. Preliminary results show that only 9 out of 37 observed objects were bright enough in X-rays to be detected with ROSAT, either in outburst or at quiescence.Three basic ...
