Sequential Star-Formation and the Near-Infrared Stellar Populations within N159
Nolan Habel, E. Sabbi, Peter Zeidler +19
We present the first results from a JWST/NIRCam study of the star-forming region N159, one of the richest H II complexes in the Large Magellanic Cloud. This region stretches over $…
LightCube: A Parsec-Resolution 3D Model of the Local Far-Ultraviolet Interstellar Radiation Field
Hannah V. Bish, J. E. G. Peek, Catherine Zucker +5
We present a three-dimensional model of the local interstellar radiation field (ISRF) in the ultraviolet (UV). Using UV flux measurements from the TD1 catalog and stellar distances…
A Detailed Analysis of Intermediate-scale Structure in Optical Extinction Curves: Expanded Census and Two-family Classification
C. M. Gunasekera, M. Decleir, K. D. Gordon +4
The features of interstellar extinction curves serve as powerful diagnostics for interstellar dust, revealing information about its composition, size distribution, and the physical…
Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves
Karl D. Gordon, Petia Yanchulova Merica-Jones, Geoffrey C. Clayton +4
Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysi…
Faint white dwarf flux standards: data and models
Ralph C. Bohlin, Susana Deustua, Gautham Narayan +7
Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the CALSPEC (calibration spectra) database 19 faint white dwarfs (WDs) with all-sky…
The updated BOSZ synthetic stellar spectral library
Szabolcs Mészáros, Ralph Bohlin, Carlos Allende Prieto +9
Context. The modeling of stellar spectra of flux standards observed by the Hubble and James Webb space telescopes requires a large synthetic spectral library that covers a wide atm…
