A new luminous supersoft X - ray source in NGC 300
Context. We report the discovery of a new luminous supersoft source, XMMU J005455.0−374117, in the nearby spiral galaxy NGC 300, in XMM-Newton observations performed on 2005 May 22 and on 2005 November 25. The source is not present in ROSAT data nor in the previous XMM-Newton observations of 2000 December/2001 January. The unique luminous supersoft source, XMMU J005510.7−373855, detected in the...
متن کاملA Luminous Recurrent Supersoft X-ray Source in Ngc 300
We report the results of XMM-Newton observations for an especially luminous supersoft X-ray source (SSS) with bolometric luminosity of 10 39 erg s −1 in the spiral galaxy NGC 300. The source was detected as a SSS in 1992 and disappeared in subsequent X-ray observations. The source was active again during recent XMM-Newton observations. It appeared to be very soft (kT ∼ 60 eV) and very luminous ...
متن کاملSupersoft X-ray Sources in M31
We report on luminous supersoft X-ray sources (SSSs) in M31. In a survey which was most sensitive to soft sources in four 8×8 regions covered by Chandra’s ACIS-S S3 CCD, we find 33 SSSs that appear to belong to M31. Two of these were first identified as SSSs through ROSAT observations. Two SSSs may be identified with symbiotics, and 2 with supernova remnants. SSSs in the disk are clustered near...
متن کاملThe supersoft X-ray source in V5116 Sagittarii - I. The high resolution spectra
Context. Classical nova explosions occur on the surface of an accreting white dwarf in a binary system. After ejection of a fraction of the envelope and when the expanding shell becomes optically thin to X-rays, a bright source of supersoft X-rays arises, powered by residual H burning on the surface of the white dwarf. While the general picture of the nova event is well established, the details...
متن کاملThe nature of the supersoft X - ray source RX J 0513 – 69
We present spectroscopy and photometry of the LMC supersoft binary system RX J0513.9-6951. We derive a refined spectroscopic period of P= 0.761± 0.004 d, which is consistent with the value obtained from long term photometric monitoring (P= 0.76278± 0.00005 d). We see bipolar outflow components of Heii and Hβ, with velocities of ∼ 3800 km s−1, strongly suggesting that the compact object is a whi...
