Observations of the recurrent M 31 transient XMMU J004215.8+411924 with Swift, Chandra, HST, and Einstein

Pietsch, W.; Barnard, R.; Garcia, M. +2 more

Context. The transient X-ray source XMMU J004215.8+411924 within M 31 was found to be in outburst again in the 2010 May 27 Chandra observation. We present results from our four Chandra and seven Swift observations that covered this outburst.
Aims: X-ray transient behaviour is generally caused by one of two things: mass accretion from a high m…

V2368 Ophiuchi: an eclipsing and double-lined spectroscopic binary used as a photometric comparison star for U Ophiuchi

Wolf, M.; Harmanec, P.; Yang, S. +8 more

The A-type star HR 6412 = V2368 Oph was used by several investigators as a photometric comparison star for the known eclipsing binary U Oph but was found to be variable by three independent groups, including us. By analysing series of new spectral and photometric observations and a critical compilation of available radial velocities, we were able …

Photometric and spectroscopic observations of asteroid (21) Lutetia three months before the Rosetta fly-by

Lara, L. M.; Lin, Z. -Y.; Duffard, R. +1 more

Context. On its journey to comet 67P/Churyumov-Gerasimenko, the International Rosetta Mission (ESA) was planned to fly-by two asteroids: (2867) Steins and (21) Lutetia. Although classified as an M-type asteroid because of its high albedo, its reflectance spectrum in the near and mid-infrared region, suggests a primitive composition, more typical o…

The plasma emission model of RBS1774

Chkheidze, N.

In the present paper we construct a self-consistent theory, interpreting the observational properties of RBS1774. It is well known that the distribution function of relativistic particles is one-dimensional at the pulsar surface. However, cyclotron instability causes an appearance of transverse momenta of relativistic electrons, which as a result,…

X-ray properties in massive galaxy clusters: XMM-Newton observations of the REFLEX-DXL sample (Corrigendum)

Zhang, Y. -Y.; Finoguenov, A.; Böhringer, H. +5 more

The article by Zhang et al. (2006, A&A, 456, 55) contains an error in Fig. 5 on page 64, in which we inadvertently re-called the mass distribution of RXCJ0528.9-3972. We note that this does not affect any results in Zhang et al. (2006). Nevertheless, we regret this error and provide an update of Fig. 5 here.
