Remarkable Spectral Variability of PDS 456

Ehud Behar, Shai Kaspi, James Reeves +3

We report on the highest to date signal-to-noise-ratio X-ray spectrum of the luminous quasar PDS 456, as obtained during two XMM-Newton orbits in September 2007. The present spectr…

Orbital periods of cataclysmic variables identified by the SDSS. VII. Four new eclipsing systems

John Southworth, C. M. Copperwheat, B T Gansicke +1

We present photometry of nine cataclysmic variable stars identified by the Sloan Digital Sky Survey, aimed at measuring the orbital periods of these systems. Four of these objects…

Neutron Capture Cross Sections for the Weak s Process

M. Heil, A. Juseviciute, F. Kaeppeler +3

In past decades a lot of progress has been made towards understanding the main s-process component that takes place in thermally pulsing Asymptotic Giant Branch (AGB) stars. During…

Time scales of the s process - from minutes to ages

F. Käppeler, S. Bisterzo, R. Gallino +7

A discussion of the time scales in the s process appears to be an approriate aspect to discuss at the occasion of 70th anniversary of Roberto Gallino, the more as this subject has…

Rotation of young stars in Cepheus OB3b

S. P. Littlefair, Tim Naylor, N. J. Mayne +2

We present a photometric study of I-band variability in the young association Cepheus OB3b. The study is sensitive to periodic variability on timescales of less than a day, to more…

Timescale of Mass Accretion in Pre-Main-Sequence Stars

D. Fedele, M. E. van den Ancker, Th. Henning +2

We present initial result of a large spectroscopic survey aimed at measuring the timescale of mass accretion in young, pre-main-sequence stars in the spectral type range K0 - M5. U…
