Publication1RXS J062518.2+733433: A new intermediate polar
We report the identification of the cataclysmic variable 1RXS J062518.2+733433 as an intermediate polar. The orbital period of the system is determined to be...
Publication3D simulations identifying the effects of varying the twist and field strength of an emerging flux tube
Aims.We investigate the effects of varying the magnetic field strength and the twist of a flux tube as it rises through the solar interior and emerges into the...
Publication9+ frequencies for V534 Tauri, a δ Scuti variable in the Pleiades. Results of the STEPHI IX campaign
New observations of V534 Tau were performed during the STEPHI IX campaign in November 1998. An overall run of 285 h of data has been collected from three sites...
PublicationA 3D sunspot model derived from an inversion of spectropolarimetric observations and its implications for the penumbral heating
Aims:I deduced a 3D sunspot model that is in full agreement with spectropolarimetric observations, in order to address the question of a possible penumbral...
PublicationA bipolar-outflow object in the field of M 36.
We have discovered an object in the field of the Galactic open cluster 36 which exhibits a nebulous tail-like structure and a high velocity outflow. We first...
PublicationA boxy bulge in the Milky Way. Inversion of the stellar statistics equation with 2MASS data
Inverting the stellar statistics equation from 2MASS star counts, we obtain the 3D density distribution of the Galactic bulge as well as its luminosity function...
