Abstract:
Near-infrared bandpasses on spaceborne observatories diverge from
their ground-based counterparts as they are free of atmospheric
telluric absorption. Available transformations between respective
filter systems in the literature rely on theoretical stellar
atmospheres, which are known to have difficulties reproducing the
observed spectral energy distributions of cool giants. We present new
transformations between the Two Micron All Sky Survey JHKS and Hubble
Space Telescope WFC3/IR F110W, F125W, and F160W photometric systems
based on synthetic photometry of empirical stellar spectra from four
spectral libraries. This sample comprises over 1000 individual stars,
which together span nearly the full H-R diagram and sample stellar
populations from the solar neighborhood out to the Magellanic Clouds,
covering a broad range of ages, metallicities, and other relevant
stellar properties. In addition to global color-dependent
transformations, we examine band-to-band differences for cool,
luminous giant stars in particular, including multiple types of
primary distance indicators.
Description:
CALSPEC is a library of spectrophotometric standards that forms the
basis of the HST absolute flux calibration scale. The majority of
observed spectra are taken with the Space Telescope Imaging
Spectrograph (STIS), WFC3/IR, and/or the Near Infrared Camera and
Multi-Object Spectrometer (NICMOS) instruments. STIS covers
0.011-1.03u at low to medium resolution with a number of
gratings/grisms; only the G750L and G750M span into the IR, with
resolutions of ∼500-1000 and ∼5000-9000, respectively over, ∼0.5-1.um.
The WFC3/IR grisms G102 and G140 together span 0.8-1.7um, at
resolutions of R=210 at 1um and 130 at 1.4um. The NICMOS grisms span
from 0.8 to 2.5u with resolution R∼200.
The original Infrared Telescope Facility (IRTF) Spectral Library
contains 226 R∼2000 spectra of 225 late-type stars at mostly solar
metallicity, taken by the SpeX prism spectrograph at the NASA IRTF on
Maunakea with coverage from 0.8 to 2.5um.
The X-shooter Spectral Library was designed to bridge the optical and
NIR for studies of intermediate- to old-aged stellar populations. As
such, it spans a wide range of spectral types and luminosity classes
with an emphasis on cool giants, including first-ascent red giants,
red supergiants, and both oxygen- and carbon-rich TP-AGB stars. As of
the third data release, the library comprises 830 spectra of 683
unique stars observed with the ultraviolet, visible, and NIR arms of
the Very Large Telescope (VLT)/X-shooter spectrograph simultaneously.
The final set of arm-merged spectra offer R∼10000 spectral coverage
from 0.35 to 2.48um.
