A new Herschel view of the young star T54: not a transitional disk?
L. Matrà, B. Merín, C. Alves de Oliveira +10
Context: Observations of transitional disks give us an understanding of the formation of planets and planetary systems such as our own. But care must be taken in the identification…
From CoRoT 102899501 to the Sun. A time evolution model of chromospheric activity on the main sequence
P. Gondoin, D. Gandolfi, M. Fridlund +7
Using a model based on the rotational modulation of the visibility of active regions, we analyse the high-accuracy CoRoT lightcurve of the active young star CoRoT102899501. Spectro…
Extreme Ultraviolet Solar Irradiance during the rising phase of solar cycle 24 observed by PROBA2/LYRA
M. Kretzschmar, I. E. Dammasch, M. Dominique +3
The Large Yield Radiometer (LYRA) is a radiometer that has monitored the solar irradiance at high cadence and in four pass bands since January 2010. Both the instrument and its spa…
Radial velocities for the Hipparcos-Gaia Hundred-Thousand-Proper-Motion project
J. H. J. de Bruijne, A. -C. Eilers
(abridged) The Hundred-Thousand-Proper-Motion (HTPM) project will determine the proper motions of ~113500 stars using a 23-year baseline. The proper motions will use the Hipparcos…
Empirical Near Infrared colors for low-mass stars and brown dwarfs in the Orion Nebula Cluster
Gaetano Scandariato, Nicola Da Rio, Massimo Robberto +2
Atmospheric and evolutionary models for low-mass stars rely on approximate assumptions on the physics of the stellar structure and the atmospheric radiative transfer. This leads to…
Herschel images of Fomalhaut. An extrasolar Kuiper Belt at the height of its dynamical activity
B. Acke, M. Min, C. Dominik +33
Fomalhaut is a young, nearby star that is suspected to harbor an infant planetary system, interspersed with one or more belts of dusty debris. We present far-infrared images obtain…
