The Near-ultraviolet Spectra of FU Orionis Accretion Disks

open access: yesThe Astrophysical Journal Letters
We present the results of the first high-sensitivity near-ultraviolet (NUV; 1800–3200 Å) survey of FU Ori objects, using the Hubble Space Telescope STIS spectrograph.

Preparing for the Early eVolution Explorer: Characterizing the Photochemical Inputs and Transit Detection Efficiencies of Young Planets Using Multiwavelength Flare Observations by TESS and Swift

open access: yesThe Astronomical Journal
Ultraviolet flare emission can drive photochemistry in exoplanet atmospheres and even serve as the primary source of uncertainty in atmospheric retrievals.

ULTRASAT: A Wide-field Time-domain UV Space Telescope

open access: yesThe Astrophysical Journal
The Ultraviolet Transient Astronomy Satellite (ULTRASAT) is scheduled to be launched to geostationary orbit in 2027. It will carry a telescope with an unprecedentedly large field of view (204 deg ^2 ) and near-ultraviolet (NUV; 230–290 nm) sensitivity ...

Laboratory Spectral Characterization of Ribbeck Aubrite: Meteorite Sample of Earth-impacting Near-Earth Asteroid 2024 BX1

open access: yesThe Planetary Science Journal
Characterization of near-Earth objects (NEOs) is critical for Earth-impact hazard assessment. Particularly crucial to our physical understanding of NEOs are laboratory spectral measurements of meteorites as they are the best and most widely available ...

Water Production Rates of the Interstellar Object 3I/ATLAS

open access: yesThe Astrophysical Journal Letters
We report the detection of water activity in the third confirmed interstellar object, 3I/ATLAS, based on ultraviolet imaging with the Neil Gehrels Swift Observatory’s Ultraviolet/Optical Telescope. Assuming a reddening of 29% between 3325.7 and 5437.8 Å,
