Gaia23bab: a new EXor
Giannini, T.; Schisano, E.; Nisini, B.; Abraham, P.; Antoniucci, S.; Biazzo, K.; Miera, F. Cruz-Saenz de; Fiorellino, E.; Gangi, M.; Kospal, A.; Kuhn, M.; Marini, E.; Nagy, Z.; Paris, D. (2024-05-16)On March 6 2023, the Gaia telescope has alerted a 2-magnitude burst from Gaia23bab, a Young Stellar Object in the Galactic plane. We observed Gaia23bab with the Large Binocular Telescope obtaining optical and near-infrared ... -
Investigating the transport of angular momentum from young stellar objects : do H2 jets from Class I YSOs rotate
Chrysostomou, A.; Bacciotti, F.; Nisini, B.; Ray, T.P.; Eisloffel, J.; Davis, C.J.; Takami, M. (2008)In this pilot study, we examine molecular jets from the embedded Class I sources, HH26 and HH72, to search, for the first time, for kinematic signatures of jet rotation from young embedded sources -
Searching for jet rotation in Class 0/I sources observed with GEMINI/GNIRS
Coffey, D.; Bacciotti, F.; Chrysostomou, A.; Nisini, B.; Davis, C. (2011-02-01)In recent years, there has been a number of detections of gradients in the radial velocity profile across jets from young stars. The significance of these results is considerable. They may be interpreted as a signature of ... -
Searching for jet rotation in Class 0/I sources observed with GEMINI/GNIRS.
Coffey, D.; Bacciotti, F.; Chrysostomou, A.; Nisini, B.; Davis, C.J. (EDP Sciences, 2011)Context: In recent years, there has been a number of detections of gradients in the radial velocity profile across jets from young stars. The significance of these results is considerable. They may be interpreted as a ... -
VLT integral field spectroscopy of embedded protostars : using near-infrared emission lines as tracers of accretion and outflow
Davis, C.J.; Cervantes, B.; Nisini, B.; Giannini, T.; Takami, M.; Whelan, E.; Smith, M.D.; Ray, T.P.; Chrysostomou, A.; Pyo, T.S. (2011-04-01)Aims. We present near-infrared spectroscopy of the forbidden emission line (FEL) and molecular hydrogen emission line (MHEL) regions at the bases of Herbig-Haro (HH) jets from seven embedded protostars: SVS 13 (the HH 7-11 ...
