The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
Orbital solutions of eight close sdB binaries and constraints on the nature of the unseen companions
S. Geier, R. H. Oestensen, U. Heber +9
The project Massive Unseen Companions to Hot Faint Underluminous Stars from SDSS (MUCHFUSS) aims at finding hot subdwarf stars (sdBs) with massive compact companions such as white…
GRO J1008-57: an (almost) predictable transient X-ray binary
M. Kühnel, S. Müller, I. Kreykenbohm +13
A study of archival RXTE, Swift, and Suzaku pointed observations of the transient high mass X-ray binary GRO J1008-57 is presented. A new orbital ephemeris based on pulse arrival t…
DUst Around NEarby Stars. The survey observational results
C. Eiroa, J. P. Marshall, A. Mora +47
Debris discs are a consequence of the planet formation process and constitute the fingerprints of planetesimal systems. Their solar system's counterparts are the asteroid and Edgew…
No anti-correlation between cyclotron line energy and X-ray flux in 4U 0115+634
Sebastian Müller, Carlo Ferrigno, Matthias Kühnel +18
We report on an outburst of the high mass X-ray binary 4U 0115+63 with a pulse period of 3.6s in 2008 March/April as observed with RXTE and INTEGRAL. During the outburst the neutro…
Sublimation Temperature of Circumstellar Dust Particles and Its Importance for Dust Ring Formation
Hiroshi Kobayashi, Hiroshi Kimura, Sei-ichiro Watanabe +2
Dust particles in orbit around a star drift toward the central star by the Poynting-Robertson effect and pile up by sublimation. We analytically derive the pile-up magnitude, adopt…
