HIGH PRECISION EFFECTIVE TEMPERATURES OF F-K SUPERGIANTS AND CLASSICAL CEPHEIDS
Odessa Astronomical Publications, 2017 We present precise effective temperatures (Teff) of 110 F-K supergiants determined from the method of line depth ratios. For each star, we have measured the line depths a large number of spectral lines of low and high excitation potentials and ...

Equivalent Width of the Interstellar Na i D1 and D2 Absorption Lines for Stars with E(B−V) < 0.15
New measurements of the equivalent width of the interstellar Na i D1 and D2 absorption lines for 62 bright B-type stars with E(B − V) < 0.15 are used to recalibrate the relation between these quantities in this low-reddening regime, and to quantify the ...

The problem with reddening distances to planetary nebulae
, 2006 It is noted that the vast majority of Galactic PNe are located outside of the interstellar reddening layer, to the extent that local gradients in E B-V are low to undetectable.

Studies of interstellar reddening
, 2018 The wavelength dependence of interstellar obscuration, in magnitudes against reciprocal wavelength, is known to be well represented, over the visible part of the spectrum, by two straight lines intersecting at or near the broad interstellar absorption band at 4430A. The existing measures, obtained principally from low dispersion objective prism spectra,

Ly Halo Properties and Dust in the Circumgalactic Medium of z ∼ 2 Star-forming Galaxies
The Astrophysical JournalWe present Keck Cosmic Web Imager integral-field unit observations around extended Ly α halos of 27 typical star-forming galaxies with redshifts 2.0 < z < 3.2 drawn from the MOSFIRE Deep Evolution Field survey.

The first glimpse of a water ice absorption map in the Milky Way
Astronomy & AstrophysicsInterstellar ice plays a key role in the thermal evolution of the interstellar medium and in astrochemical pathways, yet its large-scale distribution remains poorly constrained. We use the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All

Interstellar reddening in the galaxy
, 2019 Objective prism spectra obtained with the 16/24/60-inch Schmidt telescope have been used for an investigation of the wavelength dependence of interstellar absorption in the spectral range from 8000A to 3450A, in a region of 30 square degrees in Cygnus centred on (20ʰ15ᵐ, 38 °).

An Upper Limit of 106 M⊙ in Dust from ALMA Observations in 60 Little Red Dots
The Astrophysical Journal LettersBy virtue of their red color, the dust in little red dots (LRDs) has been thought to be of appreciable influence, whether that dust is distributed in a torus around a compact active galactic nucleus or diffuse in the interstellar medium of nascent ...
