Fundamental Parameters for Central Stars of 103 Infrared Bowshock Nebulae
Nikhil Patten, Henry A. Kobulnicky, Matthew S. Povich +16
Stellar bowshock nebulae are arcuate shock fronts formed by the interaction of radiation-driven stellar winds and the relative motion of the ambient interstellar material. Stellar…
XUE. Molecular inventory in the inner region of an extremely irradiated Protoplanetary Disk
María Claudia Ramirez-Tannus, Arjan Bik, Lars Cuijpers +24
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, that focuses on the characterization of planet forming disks in massive…
Characterizing the X-ray Emission of Intermediate-Mass Pre-Main-Sequence Stars
Evan H. Nuñez, Matthew S. Povich, Breanna A. Binder +2
We use X-ray and infrared observations to study the properties of three classes of young stars in the Carina Nebula: intermediate-mass (2--5~M) pre-main sequence stars (IMP…
The Duration of Star Formation in Galactic Giant Molecular Clouds. I. The Great Nebula in Carina
Matthew S. Povich, Jessica T. Maldonado, Evan Haze Nuñez +1
We present a novel infrared spectral energy distribution (SED) modeling methodology that uses likelihood-based weighting of the model fitting results to construct probabilistic H-R…
Mass-loss rates for O and early B stars powering bowshock nebulae: evidence for bi-stability behavior
Henry A. Kobulnicky, William T. Chick, Matthew S. Povich
Second only to initial mass, the rate of wind-driven mass loss determines the final mass of a massive star and the nature of its remnant. Motivated by the need to reconcile observa…
Circumstellar Disk Lifetimes In Numerous Galactic Young Stellar Clusters
Alexander J. W. Richert, Konstantin V. Getman, Eric D. Feigelson +5
Photometric detections of dust circumstellar disks around pre-main sequence (PMS) stars, coupled with estimates of stellar ages, provide constraints on the time available for plane…
