NIRCam yells at cloud: JWST MIRI imaging can directly detect exoplanets of the same temperature, mass, age, and orbital separation as Saturn and Jupiter
Rachel Bowens-Rubin, James Mang, Mary Anne Limbach +9
NIRCam and MIRI coronagraphy have successfully demonstrated the ability to directly image young sub-Jupiter mass and mature gas-giant exoplanets. However, these modes struggle to r…
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

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…
A HST Study of the Substellar Population of NGC 2024
Massimo Robberto, Mario Gennaro, Nicola Da Rio +6
We performed a HST/WFC3-IR imaging survey of the young stellar cluster NGC 2024 in three filters probing the 1.4~m HO absorption feature, characteristic of the population of…
StraKLIP: A novel pipeline for detection and characterization of close-in faint companions through Karhunen-Loêve Image Processing algorithm
Giovanni M. Strampelli, Laurent Pueyo, Jonathan Aguilar +3
We present a new pipeline developed to detect and characterize faint astronomical companions at small angular separation from the host star using sets of wide-field imaging observa…
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…
Nebular Spectroscopy of Kepler's Brightest Supernova
G. Dimitriadis, C. Rojas-Bravo, C. D. Kilpatrick +9
We present late-time (240-260 days after peak brightness) optical photometry and nebular (+236 and +264 days) spectroscopy of SN 2018oh, the brightest Type Ia supernova (SN I…
K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova
G. Dimitriadis, R. J. Foley, A. Rest +145
We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…
Sub-percent Photometry: Faint DA White Dwarf Spectophotometric Standards for Astrophysical Observatories
Gautham Narayan, Thomas Matheson, Abhijit Saha +18
We have established a network of 19 faint (16.5 mag 19 mag) northern and equatorial DA white dwarfs as spectrophotometric standards for present and future wide-field observ…
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
