Classical novae commonly show evidence of rapid dust formation within months of the
outburst. However, it is unclear how molecules and grains are able to condense within the …

We have imaged the ejecta of GK Persei (Nova Persei 1901 AD) with the Hubble Space
Telescope (HST), whose 0.1 arcsec resolution reveals hundreds of cometary-like structures …

I present data on the shell of classical Nova Persei (1901) obtained by the Advanced CCD
Imaging Spectrometer S3 detector on board the Chandra X-Ray Observatory. The X-ray …

We present a kinematical study of the optical ejecta of GK Per. It is based on proper-motion
measurements of 282 knots from∼ 20 images spanning 25 years. Doppler shifts are also …

The classical nova GK Persei rivaled the brightness of Vega at the peak of its outburst in
1901. Early observations showed it to possess optical nebulosities apparently expanding at …

Nova V458 Vul erupted on 2007 August 8 and reached a visual magnitude of 8.1 a few days
later. Hα images obtained 6 weeks before the outburst as part of the IPHAS Galactic plane …

We present new observations of the nebular remnant of the old nova GK Persei 1901 in the
optical using the Himalayan Chandra Telescope (HCT) and at low radio frequencies using …

Archival data on permanent superhump systems are compiled to test the thermal stability of
their accretion discs. We find that their discs are almost certainly thermally stable as …

Detecting molecular line emission from classical nova remnants has the potential to reveal
information on the composition of the ejecta, in particular accurate isotopic ratios in the …

MERLIN observations of the unusually slow nova V723 Cas are presented. Nine epochs of 6-
cm data between 1996 and 2001 are mapped, showing the initial expansion and …
