Mass determination for T Tauri stars from JHK Photometry
Tania A. Lopez-Chico, Luis Salas
We present a method that uses disk models to determine stellar masses for Pre-Main sequence T Tauri stars from JHK photometry. We find that the infrared excess produced by the disk…
Molecular Hydrogen Kinematics in Cepheus A
David Hiriart, Luis Salas, Irene Cruz-Gonzalez
We present the radial velocity structure of the molecular hydrogen outflows associated to the star forming region Cepheus A. This structure is derived from doppler shift of the H_2…
Sequential star formation at the periphery of the HII regions Sh 217 and Sh 219
L. Deharveng, A. Zavagno, L. Salas +3
The HII regions Sh 217 and Sh 219 are textbook examples of a Stromgren sphere surrounded by an annular photodissociation region (PDR). The annular PDR is observed in both the 21 cm…
Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
