Theoretical light curves of four recurrent novae in outburst are modeled to obtain various
physical parameters. The four objects studied here are those with a red giant companion, ie …

Stellar explosions such as novae and supernovae produce most of the heavy elements in
the Universe. The onset of a nova is well understood as driven by runaway thermonuclear …

An optical imaging study of old nova remnants has revealed previously unobserved features
in the shells of 13 classical novae–DQ Her, FH Ser, HR Del, GK Per, V1500 Cyg, T Aur …

Nova outbursts take place in binary star systems comprising a white dwarf and either a low-
mass Sun-like star or, as in the case of the recurrent nova RS Ophiuchi, a red giant …

We report high-resolution radio imaging of the recurrent nova RS Ophiuchi (RS Oph) during
the first month of the 2006 outburst, using the Very Long Baseline Array (VLBA) …

ABSTRACT We report Hubble Space Telescope (HST) imaging, obtained 155 and 449 days
after the 2006 outburst of the recurrent nova RS Ophiuchi, together with ground-based …

We present the first detailed kinematical analysis of the planetary nebula Abell 63, which is
known to contain the eclipsing close-binary nucleus UU Sge. Abell 63 provides an important …

We have carried out a detailed analysis of the archival high resolution spectra of the
classical nova V1974 Cyg 1992. The main UV resonance lines show P Cygni profiles in the …

Following the early Swift X-ray observations of the latest outburst of the recurrent nova RS
Ophiuchi in 2006 February (Paper I), we present new one-dimensional hydrodynamical …

High-resolution long-slit Hα spectra of the shell of the old nova DQ Herculis have been
obtained with the William Herschel Telescope using the ISIS spectrograph. An equatorial …
