ALMA polarimetric studies of rotating jet/disk systems
F. Bacciotti, J. M. Girart, M. Padovani +9
We have recently obtained polarimetric data at mm wavelengths with ALMA for the young systems DG Tau and CW Tau, for which the rotation properties of jet and disk have been investi…
Gas density perturbations induced by forming planet(s) in the AS 209 protoplanetary disk as seen with ALMA
Cécile Favre, Davide Fedele, Luke Maud +6
The formation of planets occurs within protoplanetary disks surrounding young stars, resulting in perturbation of the gas and dust surface densities. Here, we report the first evid…
Young Stars and their Variability with LSST
Rosaria Bonito, Patrick Hartigan, Laura Venuti +35
Young stars exhibit short-term photometric variability caused by mass accretion events from circumstellar disks, the presence of dusty warps within the inner disks, starspots that…
ALMA observations of polarized emission toward the CW Tau and DG Tau protoplanetary disks: constraints on dust grain growth and settling
Francesca Bacciotti, Josep Miquel Girart, Marco Padovani +9
We present polarimetric data of CW Tau and DG Tau, two well-known Class II disk/jet systems, obtained with the Atacama Large Millimeter/submillimeter Array at 870 m and 0."2 ave…
The Gaia DR2 view of the Gamma Velorum cluster: resolving the 6D structure
E. Franciosini, G. G. Sacco, R. D. Jeffries +4
Gaia-ESO Survey observations of the young Gamma Velorum cluster led to the discovery of two kinematically-distinct populations, Gamma Vel A and B, respectively, with population B e…
First Detection of the Simplest Organic Acid in a Protoplanetary Disk
Cécile Favre, Davide Fedele, Dmitry Semenov +14
The formation of asteroids, comets and planets occurs in the interior of protoplanetary disks during the early phase of star formation. Consequently, the chemical composition of th…
