Faint White Dwarf Flux Standards: Data and Models

Author(s)
ralph bohlin, Susana Deustua, ABHIJIT SAHA, Gautham Narayan, Annalisa Calamida, Ivan Hubeny, Thomas Matheson, Armin Rest, Jay Holberg, Karl Gordon, Christopher Stubbs
Abstract Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the calibration spectra (CALSPEC) database of 19 faint

Boyd, Gautham Narayan, Kaisey Mandel, Matthew Grayling, Aidan Berres, Mai Li, Aaron Do, ABHIJIT SAHA, Tim Axelrod, Thomas Matheson, Edward W Olszewski, ralph bohlin, Annalisa Calamida, Jenna Claver, Susana Deustua, Jay Holberg, Ivan Hubeny, John MacKenty, Konstantin Malanchev, Sean Points, Armin Rest, Elena Sabbi, Christopher Stubbs
standards (16.5 V 19.5) alongside the three CALSPEC standards, from 900 Å to 32 μm. The framework is the first of its kind to jointly infer photometric

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

Author(s)
Abbigail Elms, Nicola Gentile Fusillo, Pier-Emmanuel Tremblay, ralph bohlin, Mark Hollands, Snehalata Sahu, Mairi O'Brien, Susana Deustua, Tim Cunningham
The accurate flux calibration of observational data is vital for astrophysics and cosmology because absolute flux uncertainties of stellar standards propagate i
