(IOP Publishing, 2014-04)The ζ Aurigae system 31 Cygni (K4 Ib + B4 V) was observed by the FUSE satellite during total eclipse and at three phases during chromospheric eclipse. We present the coadded, calibrated spectra and atlases with line ...
-
(IOP Publishing, 2011-02-20)We present a mechanism for the crystalline silicate production associated with the formation and subsequent destruction of massive fragments in young protostellar disks. The fragments form in the embedded phase of star ...
-
(IOP Publishing Limited, 2011-03-10)We present basic properties of protostellar disks in the embedded phase of star formation (EPSF), which is difficult to probe observationally using available observational facilities. We use numerical hydrodynamics simulations ...
-
(Wiley-Blackwell, 2011-02)The results of a coordinated space-based photometric and ground-based spectroscopic observing campaign on the enigmatic γ-ray binary LS 5039 are reported. 16 d of observations from the MOST satellite have been combined ...
-
(Oxford University Press, 2012-01)We report the discovery and analysis of a very strong magnetic field in the rapidly rotating early B-type star HR 5907, based on observations obtained as part of the Magnetism in Massive Stars (MiMeS) project. We infer a ...
-
(Halifax, N.S. : Saint Mary's University, 2006)Optical coronagraphic imaging of the circumstellar dust disk around β Pictoris reveals that the inner portion of the disk is warped, and this warp is typically attributed to the presence of a planetary system. Mouillet et ...
-
(American Astronomical SocietyIOP Science, 2013-05-20)We present results from three weeks’ photometric monitoring of the magnetic helium-strong star [sigma] Ori E using the Microvariability and Oscillations of Stars microsatellite. The star’s light curve is dominated by ...
-
(European Southern ObservatoryEDP Sciences, 2006-03)We present the near-infrared speckle interferometry for LP And in the H and K’ bands with diffraction-limited resolutions of 56 and 72 mas, new JHKLM photometry, and the results of our radiative transfer modelling of this ...
-
(European Southern ObservatoryEDP Sciences, 2004-04)We present the results of optical and near-IR spectroscopic and mid-IR imaging observations of the emission-line star MWC 300. Its properties and evolutionary state are still under debate (a B[e] supergiant or a Herbig Be ...
-
(European Southern ObservatoryEDP Sciences, 2005-11)We present results of the first two-dimensional radiative transfer modelling of the eclipsing binary RY Sct and its dusty disc. Assuming an effective temperature T[subscript *] = 27 000 K for both components and the distance ...
