We present the ROSAT High Resolution Imager (HRI) data of the first resolved and detected classical nova shell in the X-ray wavelengths : The shell of Nova Persei (1901). We find that the shell is composed of knots and has an elliptical shape. The surface brightness is about 703.4+/-54.5 counts arcmin(-2). We estimate that the spectrum is of thermal origin with a luminosity of 8.0x10(31) erg s(-1) and an X-ray temperature of similar to 2.0x10(6) K in the 0.1-2.4 keV energy range. The knots are most likely a result of fragmentation and condensation in the post-shock region. This detection sheds some light into one of the most poorly understood stages of classical nova evolution. (C) 2000 COSPAR. Published by Elsevier Science Ltd.

The first resolved and detected classical nova shell in X-rays: The shell of Nova Persei 1901 Balman, Şölen; Ogelman, HB (IOP Publishing, 1999-06-20) We present the ROSAT High-Resolution Imager data of the first resolved and detected classical nova shell in the X-ray wavelengths: the shell of Nova Persei 1901. We find that the X-ray nebula is composed of knots/clumps and has an elliptical shape with a total count rate of about 0.01 +/- 0.001 counts s(-1). We estimate that the spectrum is of thermal origin with a luminosity of similar to 8.0 x 10(31) ergs s(-1) and an X-ray temperature of similar to 2.0 x 10(6) K in the 0.1-2.4 keV energy range. The knots...
An archival study of extended X-ray emission from classical and recurrent novae Balman, Şölen (2005-01-21) I discuss morphology and spectrum of the first resolved and detected classical nova shell in the X-rays - the remnant of GK Persei (1901). The existence of such a nebulosity brings about the possibility of other nova remnants emitting X-rays. I calculate that the X-ray luminosity should be about 10(26) - 10(33) ergs s(-1) on the onset of cooling for nova remnants. I have done an archival search on 250 classical and recurrent nova candidates using Chandra, XMM-Newton, ROSAT and ASCA databases. There is no si...
The XMM-Newton detection of extended emission from the nova remnant of T Pyxidis Balman, Şölen (Oxford University Press (OUP), 2010-05-01) We report the detection of an extended X-ray nebulosity with an elongation from north-east to south-west in excess of 15 arcsec in a radial profile and imaging of the recurrent nova T Pyx using the archival data obtained with the X-ray Multi-Mirror Mission (XMM-Newton), European Photon Imaging Camera (pn instrument). The signal-to-noise ratio in the extended emission (above the point source and the background) is 5.2 over the 0.3-9.0 keV energy range and 4.9 over the 0.3-1.5 keV energy range. We calculate a...
The X-ray spectral evolution of classical Nova V1974 Cygni 1992: A reanalysis of the ROSAT data Balman, Şölen; Krautter, J; Ogelman, H (IOP Publishing, 1998-05-20) We present a spectral analysis of the archival X-ray data of classical Nova V1974 Cygni 1992 (Nova Cygni 1992) obtained by the ROSAT Position Sensitive Proportional Counter (PSPC). The X-ray spectrum is fitted with a two-component model. The first component is a white dwarf atmosphere emission model developed for the remnants of classical novae near the Eddington luminosity. The model is used to fit the soft X-ray data in the similar to 0.1-1.0 keV range, where the bulk of emission is below 0.7 keV. The sec...
The CHANDRA observation of the first resolved and detected classical nova shell in X-rays: The shell of Nova Persei 1901 (GK Per) Balman, Şölen (2000-09-09) I present the CHANDRA ACIS-S data of the classical nova shell of Nova Persei (1901). The X-ray nebula is detected with a count rate of 0.10+/-0.003 c s(-1). It is asymmetric with bulk of emission on the southwestern quadrant. The X-ray emission from the vicinity of the radio ridge is detected as an arc that covers from west to south of the central source. The X-ray spectrum consists at least of two components of emission. The lower temperature component (below 2 keV) has kT 0.15+/-0.02 keV with an X-ray flu...
