Water in Star-Forming Regions with the Herschel Space Observatory (WISH): Overview of key program and first results
E. F. van Dishoeck, L. E. Kristensen, A. O. Benz +12
`Water In Star-forming regions with Herschel' (WISH) is a key program on the Herschel Space Observatory designed to probe the physical and chemical structure of young stellar objec…
CORS Baade-Wesselink method in the Walraven photometric system: the Period-Radius and the Period-Luminosity relation of Classical Cepheids
R. Molinaro, V. Ripepi, M. Marconi +4
We present a new derivation of the CORS Baade-Wesselink method in the Walraven photometric system. We solved the complete Baade-Wesselink equation by calibrating the surface bright…
Inference from adiabatic analysis of solar-like oscillations in Red giants
Josefina Montalban, Andrea Miglio, Arlette Noels +2
The clear detection with CoRoT and KEPLER of radial and non-radial solar-like oscillations in many red giants paves the way to seismic inferences on the structure of such stars. We…
An optical and HI study of the dwarf Local Group galaxy VV124=UGC4879. A gas-poor dwarf with a stellar disk?
M. Bellazzini, G. Beccari, T. A. Oosterloo +8
We present a detailed study of the dwarf galaxy VV124, recently recognized as a isolated member of the Local Group. We have obtained deep (r=26.5) wide-field g,r photometry of indi…
Line shape effects on intensity measurements of solar features: Brightness correction to SoHO MDI continuum images
S. Criscuoli, I. Ermolli, D. Del Moro +4
Continuum intensity observations obtained with the Michelson Doppler Imager (MDI) on-board the SoHO mission provide long time series of filtergrams that are ideal for studying the…
Metallicity Diagnostics with Infrared Fine-Structure Lines
Tohru Nagao, Roberto Maiolino, Alessandro Marconi +1
Although measuring the gas metallicity in galaxies at various redshifts is crucial to constrain galaxy evolutionary scenarios, only rest-frame optical emission lines have been gene…
