HST Survey of the Orion Nebula Cluster in ACS/Visible and WFC3/IR Bands. IV. A Bayesian multi-wavelength study of stellar parameters in the ONC
Giovanni M. Strampelli, Massimo Robberto, Laurent Pueyo +4
We have performed a comprehensive study of the Orion Nebula Cluster (ONC) combining the photometric data obtained by the two \textit{HST} Treasury programs that targeted this regio…
Searching for a Hypervelocity White Dwarf Companion: A Proper Motion Survey of SN 1006
Joshua V. Shields, Wolfgang Kerzendorf, Matthew W. Hosek +7
Type Ia Supernovae (SNe Ia) are securely understood to come from the thermonuclear explosion of a white dwarf as a result of binary interaction, but the nature of that binary inter…
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: 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…
The not so simple stellar system Omega Cen. II. Evidence in support of a merging scenario
Annalisa Calamida, Alice Zocchi, Giuseppe Bono +7
We present multi-band photometry covering 5° 5°across Cen collected with the Dark Energy Camera, combined to Hubble Space Telescope and Wide Field Imager data fo…
Light-echoes from the plateau in Eta Carinae's Great Eruption reveal a two-stage shock-powered event
Nathan Smith, Jennifer E. Andrews, Armin Rest +7
We present multi-epoch photometry and spectroscopy of a light echo from eta Carinae's 19th century Great Eruption. This echo shows a steady decline over a decade, sampling the 1850…
A Search for a Surviving White Dwarf Companion in SN 1006
W. E. Kerzendorf, G. Strampelli, K. J. Shen +5
Multiple channels have been proposed to produce Type Ia supernovae, with many scenarios suggesting that the exploding white dwarf accretes from a binary companion pre-explosion. In…
Connecting the progenitors, pre-explosion variability, and giant outbursts of luminous blue variables with Gaia16cfr
Charles D. Kilpatrick, Ryan J. Foley, Maria R. Drout +10
We present multi-epoch, multi-colour pre-outburst photometry and post-outburst light curves and spectra of the luminous blue variable (LBV) outburst Gaia16cfr discovered by the Gai…
The soundtrack of RR Lyrae in Omega Cen at high-frequency
A. Calamida, S. K. Randall, M. Monelli +8
We present preliminary Sloan u',g'-band light curves for a sample of known RR Lyrae variables in the Galactic globular cluster Omega Cen. Results are based on the partial reduction…
