Light Curves and Colors of the Ejecta from Dimorphos after the DART Impact
Ariel Graykowski, Ryan A. Lambert, Franck Marchis +41
On 26 September 2022 the Double Asteroid Redirection Test (DART) spacecraft impacted Dimorphos, a satellite of the asteroid 65803 Didymos. Because it is a binary system, it is poss…
Design Requirements for the Wide-field Infrared TransientExplorer (WINTER)
Danielle Frostig, John W. Baker, Joshua Brown +11
The Wide-field Infrared Transient Explorer (WINTER) is a 1x1 degree infrared survey telescope under development at MIT and Caltech, and slated for commissioning at Palomar Observat…
Constraints on Metastable Helium in the Atmospheres of WASP-69b and WASP-52b with Ultra-Narrowband Photometry
Shreyas Vissapragada, Heather A. Knutson, Nemanja Jovanovic +7
Infrared observations of metastable 2S helium absorption with ground- and space-based spectroscopy are rapidly maturing, as this species is a unique probe of exoplanet atmosphe…
Magnetic field amplification in nonlinear diffusive shock acceleration including resonant and non-resonant cosmic-ray driven instabilities
Andrei M. Bykov, Donald C. Ellison, Sergei M. Osipov +1
We present a nonlinear Monte Carlo model of efficient diffusive shock acceleration (DSA) where the magnetic turbulence responsible for particle diffusion is calculated self-consist…
Discovery and Early Multi-Wavelength Measurements of the Energetic Type Ic Supernova PTF12gzk: A Massive-Star Explosion in a Dwarf Host Galaxy
Sagi Ben-Ami, Avishay Gal-Yam, Alexei V. Filippenko +45
We present the discovery and extensive early-time observations of the Type Ic supernova (SN) PTF12gzk. Our finely sampled light curves show a rise of 0.8mag within 2.5hr. Power-law…
High resolution spectroscopic study of red clump stars in the Galaxy: iron group elements
E. Puzeras, G. Tautvaisiene, J. G. Cohen +4
The main atmospheric parameters and abundances of the iron group elements (vanadium, chromium, iron, cobalt and nickel) are determined for 62 red giant "clump" stars revealed in th…
