AT 2016dah and AT 2017fyp: the first classical novae discovered within a tidal stream [PDF]

, 2022
AT2016dah and AT2017fyp are fairly typical Andromeda Galaxy (M31) classical novae. AT2016dah is an almost text book example of a 'very fast' declining, yet uncommon, Fe II'b' (broad-lined) nova, discovered during the rise to peak optical luminosity, and ...

Spectral evolution of the extremely fast classical nova V838 Herculis [PDF]

Astronomy and Astrophysics, 2010
Spectral evolution of nova V838 Her 1991 was monitored at Asiago Astrophysical Observatory from 1991 March 31 to July 2. The spectra in the early decline stage showed emission lines of H I, He I, He II, N II, N III, C II, C III, C IV, Si II, [S III], [Ne III], and Fe II, where some identifications are different from those reported in the previous works.

V1494 Aql: Eclipsing Fast Nova with an Unusual Orbital Light Curve [PDF]

Publications of the Astronomical Society of Japan, 2004
Abstract We present the time-resolved photometry of V1494 Aql (Nova Aql 1999 No. 2) between 2001 November and 2003 June. The object is confirmed to be an eclipsing nova with a period of 0.1346138(2) d. The eclipses were present in all observed epochs.

The 1999 Optical Outburst of the Fast X-Ray Nova, V4641 Sagittarii [PDF]

Publications of the Astronomical Society of Japan, 2002
We report on the detection of an optical outburst which preceded the X-ray main flare of the fast X-ray nova V4641 Sagittarii. The object became active since early August 1999, and then experienced an optical outburst reaching 8.8 mag on 1999 September 15. The observed maximum was between two X-ray flares, that is, 12.1 hr after the X-ray sub-flare and

Individuals With Multijoint Osteoarthritis Demonstrate Larger Longitudinal Declines in Frailty: Data From the Canadian Longitudinal Study on Aging

Arthritis Care &Research, EarlyView.
Objective The aim of this study was to test the hypothesis that multijoint osteoarthritis would modify the relation between time and frailty progression, in which more affected joints would lead to larger declines over six years compared to those without osteoarthritis using data from the Canadian Longitudinal Study on Aging.

Optical observations of the fast nova V1674 Herculis

Monthly Notices of the Royal Astronomical Society
ABSTRACT We present the evolution of optical spectra and light curves of the fast nova V1674 Herculis during 150 d past its eruption. Using the post-eruption AAVSO light curve, we have calculated the orbital period of V1674 Her to be 0.153 d. There is no unambiguous white dwarf spin period in our data.

The First Orbital Period of a Very Bright and Fast Nova in M31: M31N 2013-01b [PDF]

The Astrophysical Journal, 2018
Abstract We present the first X-ray and UV/optical observations of a very bright and fast nova in the disk of M31, M31N 2013-01b. The nova reached a peak magnitude R ∼ 15 mag and decayed by 2 mag in only 3 days, making it one of the brightest and fastest novae ever detected in Andromeda.

Recurrent novae [PDF]

, 1993
Recurrent novae seem to be a rather inhomogeneous group: T CrB is a binary with a M III companion; U Sco probably has a late dwarf as companion. Three are fast novae; two are slow novae. Some of them appear to have normal chemical composition; others may

A WISE view of novae - I. The data [PDF]

, 2014
We present the results of data-mining the Wide-field Infrared Survey Explorer (WISE) archive for data on classical and recurrent novae. We find that the detections are consistent with dust emission, line emission, emission by a stellar photosphere, or a ...
