HST Stellar Standards with 1% Accuracy in Absolute Flux

  title={HST Stellar Standards with 1\% Accuracy in Absolute Flux},
  author={Ralph C. Bohlin},
Free of any atmospheric contamination, HST provides the best available spectrophotometry from the far-UV to the near-IR for stars as faint as V~16. The HST CALSPEC standard star network is based on 3 standard candles: the hot, pure hydrogen white dwarf (WD) stars G191B2B, GD153, and GD71, which have Hubeny NLTE model flux calculations that require the atomic physics for only one atom. These model flux distributions are normalized to the absolute flux for Vega of 3.46x10^{-9} erg cm^{-2} s^{-1… 
Building up a database of spectro-photometric standard stars from the UV to the near-IR: a status report
We present a project aimed at establishing a set of 12 spectro-photometric standards over a wide wavelength range from 320 to 2500 nm. Currently no such set of standard stars covering the near-IR is
Precision angular diameters for 16 southern stars with VLTI/PIONIER
In the current era of Gaia and large, high signal to noise stellar spectroscopic surveys, there is an unmet need for a reliable library of fundamentally calibrated stellar effective temperatures
Gemini planet imager observational calibrations VI: photometric and spectroscopic calibration for the integral field spectrograph
The Gemini Planet Imager (GPI) is a new facility instrument for the Gemini Observatory designed to provide direct detection and characterization of planets and debris disks around stars in the solar
ACCESS: absolute color calibration experiment for standard stars
ACCESS is a recently approved rocket-borne payload with a ground-based calibration and performance monitoring program that is designed to transfer the National Institute of Standards and Technology
Photometric calibration of the Supernova Legacy Survey fields
Aims: We present the photometric calibration of the Supernova Legacy Survey (SNLS) fields. The SNLS aims at measuring the distances to SNe Ia at (0.3 < z < 1) using MegaCam, the 1 deg2 imager on the
ACCESS: Enabling an Improved Flux Scale for Astrophysics
Improvements in the precision of the astrophysical flux scale are needed to answer fundamental scientific questions ranging from cosmology to stellar physics. The unexpected discovery that the
When flux standards go wild: white dwarfs in the age of Kepler
White dwarf stars have been used as flux standards for decades, thanks to their staid simplicity. We have empirically tested their photometric stability by analyzing the light curves of 398
Synthetic photometry for M and K giants and stellar evolution: hydrostatic dust-free model atmospheres and chemical abundances
Based on a grid of hydrostatic spherical COMARCS models for cool stars, we have calculated observable properties of these objects, which will be mainly used in combination with stellar evolution
Theoretical model atmosphere spectra used for the calibration of infrared instruments
Context. One of the key ingredients in establishing the relation between input signal and output flux from a spectrometer is accurate determination of the spectrophotometric calibration. In the case
Optical Region Spectrophotometry: Past and Present
In the 1960s and 1970s optical region spectrophotometry achieved the status of a major tool in stellar research. New instrumentation, rotating grating scanners using photomultiplier tubes as

1.0 Abstract We present a discussion of the methods that can be used to model the JWST Point Spread Function (PSF) and illustrate some of the potential impacts of the PSF properties on the scientific
New atlases for solar flux, irradiance, central intensity, and limb intensity
I have produced a revised FTS Kitt Peak Solar Flux Atlas for 300 to 1000 nm (Kurucz 2005) and a new high resolution Kitt Peak Irradiance Atlas from 300 to 1000 nm with the telluric lines removed. I
