Second Timescale Photometry of the Very Fast Nova V1674 Her with Palomar Gattini-IR

Research Notes of the AAS, 2021
Abstract We report second-timescale infrared photometry of the nova V1674 Her using Palomar Gattini-IR (PGIR). These observations constitute the first infrared and highest temporal resolution data (resolution of ≈0.84 s) of the nova reported to date.

X-ray monitoring of classical novae in the central region of M 31. II. Autumn and winter 2007/2008 and 2008/2009 [PDF]

, 2010
[Abridged] Classical novae (CNe) represent the major class of supersoft X-ray sources (SSSs) in the central region of our neighbouring galaxy M 31. We performed a dedicated monitoring of the M 31 central region with XMM-Newton and Chandra between Nov ...

Rms–flux relation and fast optical variability simulations of the nova-like system MV Lyr [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
The stochastic variability (flickering) of the nova-like system (subclass of cataclysmic variable) MV Lyr yields a complicated power density spectrum with four break frequencies. Scaringi et al. (2012) analysed high-cadence Kepler data of MV Lyr, taken almost continuously over 600 days, giving the unique opportunity to study multicomponent Power ...

Pre-maximum and maximum of Novae: The spectroscopic observations of Nova ASASSN-17hx [PDF]

, 2018
The coverage of the pre-maximum stage of novae is sparse, with the exception of a few slow novae where the pre-maximum duration is of the order of some weeks.

Swift X-Ray Observations of Classical Novae. II. The Super Soft Source sample

, 2011
The Swift GRB satellite is an excellent facility for studying novae. Its rapid response time and sensitive X-ray detector provides an unparalleled opportunity to investigate the previously poorly sampled evolution of novae in the X-ray regime. This paper

Comprehensive Listing of 208 Nova White Dwarf Masses as the Primary Determinant of Spectral Class and Light-curve Class

The Astrophysical Journal
For Galactic novae, I calculate and collect a comprehensive catalog of 208 measures of white dwarf (WD) masses ( M _WD ) and 232 measures of average V magnitudes in quiescence ( V _q ). These are collected into a comprehensive catalog of most fundamental

The critical mass ratio for W UMa-type contact binary systems [PDF]

Serbian Astronomical Journal
Contact binaries are close binary systems in which both components fill their inner Roche lobes so that the stars are in direct contact, and in potential mass and energy exchange.

Spectropolarimetric Evidence of Asymmetric Outburst in the Fast Nova V1494 Aquilae

The Astrophysical Journal, 2001
We present our extended polarimetric observations of a fast nova from the premaximum to transition stages. The observations were made for V1494 Aquilae (=Nova Aql 1999 No. 2) at the Dodaira Observatory of the National Astronomical Observatory of Japan between 1999 December 2 and 2000 March 29. We discovered that the light from the nova had already been

A Nova Outburst Powered by Shocks [PDF]

, 2017
Classical novae are runaway thermonuclear burning events on the surfaces of accreting white dwarfs in close binary star systems, sometimes appearing as new naked-eye sources in the night sky.
