Rate of caustic crossing microlensing events in stellar binary lenses with significant orbital motion
Arjun Murlidhar, B. Scott Gaudi, Todd. A. Thompson
Binary lens microlensing events in which the source crosses a caustic produce sharp, distinctive magnification peaks and can therefore be readily identified. In this paper, we expl…
Mid-Infrared Colors Vary with Galactic Environment: Contrasting Star-Forming Disks, Young Centers, and Quiescent Star-Formation Deserts
Debosmita Pathak, Karin M. Sandstrom, Adam K. Leroy +27
We present pc-resolution JWST/MIRI and NIRCam measurements of mid-infrared (mid-IR) color variations in the diffuse interstellar medium (ISM) of 71 nearby star-forming…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
JWST Observations of Starbursts: PAHs Closely Trace the Cool Phase of M82's Galactic Wind
Sebastian Lopez, Colton Ring, Adam K. Leroy +30
Stellar feedback drives multiphase gas outflows from starburst galaxies, but the interpretation of dust emission in these winds remains uncertain. To investigate this, we analyze n…
Hidden in Plain Sight II: Characterizing the luminous companion to Kappa Velorum with VLTI/GRAVITY
D. M. Rowan, S. Kraus, Todd A. Thompson
Kappa Velorum (Markeb, HD 81188) is one of the brightest stars in the Southern sky and has long been known to be a single-lined spectroscopic binary. The binary mass function is la…
The structure and evolution of a high-mass stellar merger in the Hertzsprung gap
Rachel A. Patton, Marc H. Pinsonneault, Todd A. Thompson
Post-main-sequence binary mergers are a common evolutionary pathway for massive stars, but the effects of merging on the long-term structure and evolution of the resulting star are…
