Stellar Parameter Determination from Photometry using Invertible Neural Networks
Victor F. Ksoll, Lynton Ardizzone, Ralf Klessen +7
Photometric surveys with the Hubble Space Telescope (HST) allow us to study stellar populations with high resolution and deep coverage, with estimates of the physical parameters of…
HST astrometry in the Orion Nebula Cluster: census of low-mass runaways
Imants Platais, Massimo Robberto, Andrea Bellini +6
We present a catalog of high-precision proper motions in the Orion Nebula Cluster (ONC), based on Treasury Program observations with the Hubble Space Telescope's (HST) ACS/WFC came…
HST survey of the Orion Nebula Cluster in the HO 1.4 m absorption band: III. The population of sub-stellar binary companions
Giovanni M. Strampelli, Jonathan Aguilar, Laurent Pueyo +4
We present new results concerning the sub-stellar binary population in the Orion Nebula Cluster (ONC). Using the Karhunen-Loève Image Projection (KLIP) algorithm, we have reprocess…
HST survey of the Orion Nebula Cluster in the HO 1.4 m absorption band: II. The substellar IMF down to planetary masses
Mario Gennaro, Massimo Robberto
We exploit the ability of the Hubble Space Telescope to probe near infrared water absorption present in the atmosphere of low-mass stars, brown dwarfs and planetary mass objects to…
HST survey of the Orion Nebula Cluster in the HO 1.4 m absorption band: I. A census of substellar and planetary mass objects
Massimo Robberto, Mario Gennaro, Maria Giulia Ubeira Gabellini +15
In order to obtain a complete census of the stellar and sub-stellar population, down to a few M in the Myr old Orion Nebula Cluster, we used the infrared channel of…
Time-domain study of the young massive cluster Westerlund 2 with the Hubble Space Telescope. I
E. Sabbi, M. Gennaro, J. Anderson +9
Time-domain studies of pre-main sequence stars have long been used to investigate star properties during their early evolutionary phases and to trace the evolution of circumstellar…
The young stellar content of the giant HII regions M8, G333.6-0.2, and NGC6357 with VLT/KMOS
M. C. Ramírez-Tannus, J. Poorta, A. Bik +14
Context: The identification and characterisation of populations of young massive stars in (giant) HII regions provides important constraints on i) the formation process of massive…
The Age of the Old Metal-Poor Globular Cluster NGC6397 Using WFC3/IR Photometry
Matteo Correnti, Mario Gennaro, Jason S. Kalirai +2
Globular Clusters (GCs) in the Milky Way represent the ideal laboratory to establish the age of the oldest stellar populations and to measure the color-magnitude relation of stars.…
Constraining Globular Cluster Age Uncertainties Using the IR Color-Magnitude Diagram
Matteo Correnti, Mario Gennaro, Jason S. Kalirai +2
Globular Clusters (GCs) in the Milky Way are the primary laboratories for establishing the ages of the oldest stellar populations and for measuring the color-magnitude relation of…
Proper motions of molecular hydrogen outflows in the Rho Ophiuchi molecular cloud
M. Zhang, W. Brandner, H. Wang +6
We aim to take a census of molecular hydrogen emission line objects (MHOs) in the Rho Ophiuchi molecular cloud and to make the first systematic proper motion measurements of these…
On the evolutionary and pulsation mass of Classical Cepheids: III. the case of the eclipsing binary Cepheid CEP0227 in the Large Magellanic Cloud
P. G. Prada Moroni, M. Gennaro, G. Bono +6
We present a new Bayesian approach to constrain the intrinsic parameters (stellar mass, age) of the eclipsing binary system CEP0227 in the LMC. We computed evolutionary models cove…
The clustered nature of star formation. Pre--main-sequence clusters in the star-forming region NGC 602/N90 in the Small Magellanic Cloud
Dimitrios A. Gouliermis, Stefan Schmeja, Andrew E. Dolphin +3
Located at the tip of the wing of the Small Magellanic Cloud (SMC), the star-forming region NGC602/N90 is characterized by the HII nebular ring N90 and the young cluster of pre--ma…
Testing pre-main sequence models: the power of a Bayesian approach
Mario Gennaro, Pier Giorgio Prada Moroni, Emanuele Tognelli
Pre-main sequence (PMS) models provide invaluable tools for the study of star forming regions as they allow to assign masses and ages to young stars. Thus it is of primary importan…
Disk Evolution in OB Associations - Deep Spitzer/IRAC Observations of IC 1795
Veronica Roccatagliata, Jeroen Bouwman, Thomas Henning +5
We present a deep Spitzer/IRAC survey of the OB association IC 1795 carried out to investigate the evolution of protoplanetary disks in regions of massive star formation. Combining…
