Evidence for reduced magnetic braking in polars from binary population models
(Royal Astronomical Society, 2020)
We present the first population synthesis of synchronous magnetic cataclysmic variables, called polars, taking into account the effect of the white dwarf (WD) magnetic field on angular momentum loss. We implemented the ...
A two-armed pattern in flickering maps of the nova-like variable UU aquarii
(UNIV CHICAGO PRESS, 2008)
We report the analysis of a uniform sample of 31 light curves of the nova-like variable UU Aqr with eclipse-mapping techniques. The data were combined to derive eclipse maps of the average steady-light component, the ...
THE SPECTRAL EVOLUTION AND EJECTA OF RECURRENT NOVA U Sco IN THE 2010 OUTBURST
(IOP PUBLISHING LTD, 2010)
Synoptic spectroscopic observations of the U Sco 2010 outburst from maximum light to quiescence as well as a contemporaneous X-ray observation are presented and analyzed. The X-ray spectrum 52 days after outburst indicates ...
The peculiar nova V1309 Scorpii/nova Scorpii 2008 A candidate twin of V838 Monocerotis
(EDP SCIENCES S A, 2010)
Aims. Nova Scorpii 2008 was the target of our Director Discretionary Time proposal at VLT+UVES in order to study the evolution, origin and abundances of the heavy-element absorption system recently discovered in 80% of ...
INTEGRAL View on cataclysmic variables and symbiotic binaries
(Elsevier, 2020-12)
Accreting white dwarfs (WDs) constitute a significant fraction of the hard X-ray sources detected by the INTEGRAL observatory. Most of them are magnetic Cataclysmic Variables (CVs) of the intermediate polar (IP) and polar ...
Quest for the Donor Star in the Magnetic Precataclysmic Variable V1082 Sgr
(IOP Publishing, 2018-12-07)
We obtained high-resolution spectra and multicolor photometry of V1082 Sgr to study the donor star in this 20.8 hr orbital period binary, which is assumed to be a detached system. We measured the rotational velocity (v sin ...
