DAmodel: Hierarchical Bayesian Modelling of DA White Dwarfs for Spectrophotometric Calibration

Benjamin M. Boyd, Gautham Narayan, Kaisey S. Mandel +17

We use hierarchical Bayesian modelling to calibrate a network of 32 all-sky faint DA white dwarf (DA WD) spectrophotometric standards () alongside three CALSPEC st…

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…

A network of cooler white dwarfs as infrared standards for flux calibration

Abbigail K. Elms, Nicola Pietro Gentile Fusillo, Pier-Emmanuel Tremblay +6

The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate into scientific resul…

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…

Hubble spectroscopy of LB-1: comparison with B+black-hole and Be+stripped-star models

D. J. Lennon, J. Maíz Apellániz, A. Irrgang +10

LB-1 has variously been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary, or a Be star plus an inflated stripped star (Be+Bstr) binary. The Space Telescope…

HSTCosmicrays: A Python Package for Analyzing Cosmic Rays in HST Calibration Data

N. D. Miles, S. Deustua, G. Tancredi

HSTCosmicrays is a python-based pipeline designed to find and characterize cosmic rays found in dark frames (exposures taken with the shutter closed). Dark exposures are obtained r…
