The Mdot - M* relation of pre-main sequence stars: a consequence of X-ray driven disc evolution
B. Ercolano, D. Mayr, J. E. Owen +2
We analyse current measurements of accretion rates onto pre-main sequence stars as a function of stellar mass, and conclude that the steep dependance of accretion rates on stellar…
Time Monitoring of Radio Jets and Magnetospheres in the Nearby Young Stellar Cluster R Coronae Australis
Hauyu Baobab Liu, Roberto Galván-Madrid, Jan Forbrich +9
We report JVLA 8-10 GHz (=3.0-3.7 cm) monitoring observations toward the YSO cluster R Coronae Australis (R\,CrA), taken in 2012, from March 15 to September 12. These observatio…
A UV-to-MIR monitoring of DR Tau: exploring how water vapor in the planet formation region of the disk is affected by stellar accretion variability
Andrea Banzatti, Michael R. Meyer, Carlo F. Manara +2
Young stars are known to show variability due to non-steady mass accretion rate from their circumstellar disks. Accretion flares can produce strong energetic irradiation and heatin…
X-Shooter spectroscopy of young stellar objects: IV -- Accretion in low-mass stars and sub-stellar objects in Lupus
J. M. Alcalá, A. Natta, C. F. Manara +11
We present X-Shooter/VLT observations of a sample of 36 accreting low-mass stellar and sub-stellar objects (YSOs) in the Lupus star forming region, spanning a range in mass from ~0…
X-Shooter spectroscopy of young stellar objects III. Photospheric and chromospheric properties of Class III objects
B. Stelzer, A. Frasca, J. M. Alcala +7
We analyzed X-Shooter/VLT spectra of 24 ClassIII sources from three nearby star-forming regions (sigmaOrionis, LupusIII, and TWHya). We determined the effective temperature, surfac…
Accurate determination of accretion and photospheric parameters in Young Stellar Objects: the case of two candidate old disks in the Orion Nebula Cluster
C. F. Manara, G. Beccari, N. Da Rio +5
Current planet formation models are largely based on the observational constraint that protoplanetary disks have lifetime 3Myr. Recent studies, however, report the existence of PMS…
