Detection of warm water vapour in Taurus protoplanetary discs by Herschel
P. Riviere-Marichalar, F. Ménard, W. F. Thi +12
Line spectra of 68 Taurus T Tauri stars were obtained with the Herschel-PACS (Photodetector Array Camera & Spectrometer) instrument as part of the GASPS (Gas Evolution in Protoplan…
High spatial resolution imaging of the star with a transiting planet WASP-33
Andy Moya, Herve Bouy, Franck Marchis +2
The recent discovery of a transiting planet around WASP-33, the misalignment of the stellar rotation axis and the planet orbit, the possible existence of an additional planet in th…
Magnetic activity and accretion on FU Tau A: Clues from variability
Aleks Scholz, Beate Stelzer, Grainne Costigan +5
FU Tau A is a young very low mass object in the Taurus star forming region which was previously found to have strong X-ray emission and to be anomalously bright for its spectral ty…
Spectroscopy of Very Low Mass Stars and Brown Dwarfs in the Lambda Orionis Star Forming Region. I. Enlarging the census down to the planetary mass domain in Collinder 69
A. Bayo, D. Barrado, J. Stauffer +7
Whilst there is a generally accepted evolutionary scheme for the formation of low-mass stars, the analogous processes when moving down in mass to the brown dwarfs regime are not ye…
The substellar population of Sigma Orionis: A deep wide survey
V. J. S. Béjar, M. R. Zapatero Osorio, R. Rebolo +5
We present a deep I,Z photometric survey covering a total area of 1.12 deg^{2} of the Sigma Orionis cluster (Icompl=22 and Zcompl=21.5mag). From I, I-Z color-magnitude diagrams we…
YSOVAR: the first sensitive, wide-area, mid-IR photometric monitoring of the ONC
M. Morales-Calderón, J. R. Stauffer, L. A. Hillenbrand +33
We present initial results from time series imaging at infrared wavelengths of 0.9 sq. degrees in the Orion Nebula Cluster (ONC). During Fall 2009 we obtained 81 epochs of Spitzer…
