NESS II Infrared and Sub-mm results

Listed in IVOA Registry (Virtual Observatory)

The Nearby Evolved Stars Survey (NESS) is a volume-complete sample of ~850 Galactic evolved stars within 3 kpc at (sub-)mm wavelengths, observed in the CO J = (2-1) and (3-2) rotational lines, and the sub-mm continuum, using the James Clark Maxwell Telescope and Atacama Pathfinder Experiment.

Description

NESS consists of five tiers, based on distances and dust-production rate (DPR). We define a new metric for estimating the distances to evolved stars and compare its results to Gaia EDR3.

Replicating other studies, the most-evolved, highly enshrouded objects in the Galactic Plane dominate the dust returned by our sources, and we initially estimate a total DPR of 4.7

  • 10^-5^ M_{sun}_ yr^-1^ from our sample. Our sub-mm fluxes are systematically higher and spectral indices are typically shallower than dust models typically predict. The 450/850 {mu}m spectral indices are consistent with the blackbody Rayleigh-Jeans regime, suggesting a large fraction of evolved stars have unexpectedly large envelopes of cold dust.
