123-321 models of classical novae
(EDP Sciences, 2020-01-28)
Article
Accés obert
Realitzat a/amb: Università di PisaContext. High-resolution spectroscopy has revealed large concentrations of CNO and sometimes other intermediate-mass elements (e.g., Ne, Na, Mg, or Al, for ONe novae) in the shells ejected during nova outbursts, suggesting ... -
Breaking the habit: the peculiar 2016 eruption of the unique recurrent nova M31N 2008-12a

Multi-dimensional simulations of mixing in classical novae
(Universitat Politècnica de Catalunya, 2011-11-03)
Tesi
Accés obertClassical nova explosions are stellar explosions that take place in close binary systems with an energy release only exceeded by gamma-ray bursts and supernova explosions. Matter from the white dwarf flows through the inner ... -
Nova LMC 2009a as observed with XMM–Newton, compared with other novae
(Oxford University Press, 2021-05-21)
Article
Accés obert<jats:title>ABSTRACT</jats:title> <jats:p>We examine four high-resolution reflection grating spectrometers (RGS) spectra of the February 2009 outburst of the luminous recurrent nova LMC 2009a. They were ... -
Population-based identification of H a-excess sources in the Gaia DR2 and IPHAS catalogues
(Oxford University Press, 2021-07-01)
Article
Accés obertWe present a catalogue of point-like H a-excess sources in the Northern Galactic Plane. Our catalogue is created using a new technique that leverages astrometric and photomeric information from Gaia to select H a-bright ... -
The Compact binary HIgh CAdence Survey (CHiCaS): An overview
(2020-09-01)
Article
Accés obert
Realitzat a/amb: European Southern Observatory / University of Warwick / Universidade de São Paulo / European Southern Observatory Chile / Centro de Estudios de Física del Cosmos de AragónCataclysmic Variables (CVs) are binaries in which a white dwarf accretes from a low-mass companion star. CVs are the best-suited laboratories to test our understanding of the evolution of compact, interacting binaries as ... -
The orbital period of the recurrent nova V2487 Oph revealed
(Oxford University Press, 2023-10-12)
Article
Accés obertWe present the first reliable determination of the orbital period of the recurrent nova V2487 Oph (Nova Oph 1998). We derived a value of 0.753 ± 0.016 d (18.1 ± 0.4 h) from the radial velocity curve of the intense He¿II ... -
Towards a volumetric census of close white dwarf binaries - I. Reference samples
(Oxford University Press, 2021-03-16)
Article
Accés obertClose white dwarf binaries play an important role across a range of astrophysics, including thermonuclear supernovae, the Galactic low-frequency gravitational wave signal, and the chemical evolution of the Galaxy. Progress ...
