Estimating Distances from Parallaxes. V. Geometric and Photogeometric Distances to 1.47 Billion Stars in Gaia Early Data Release 3

Stellar distances constitute a foundational pillar of astrophysics. The publication of 1.47 billion stellar parallaxes from Gaia is a major contribution to this. Despite Gaia’s precision, the

Luminous Stars in the Northern Milky Way

Gaia DR2 data and the evolutionary status of eight high-velocity hot post-AGB candidates

From Gaia DR 2 data of eight high velocity hot post-AGB candidates LS 3593, LSE 148, LS 5107, HD 172324, HD 214539, LS IV -12 111, LS III +52 24, and LS 3099, we found that six of them have accurate

High-resolution spectroscopy of the high-velocity hot post-AGB star IRAS 18379–1707 (LS 5112)

The high-resolution ($R\sim48\,000$) optical spectrum of the B-type supergiant LS 5112, identified as the optical counterpart of the post-AGB candidate IRAS 18379-1707, is analysed. We report the

A 3D Dust Map Based on Gaia, Pan-STARRS 1, and 2MASS

A new three-dimensional map of dust reddening, based on Gaia parallaxes and stellar photometry from Pan-STARRS 1 and 2MASS, is presented, which infer the distances, reddenings, and types of 799 million stars.

Chemical abundances of hot post-AGB stars

Context. Hot post-AGB stars are luminous objects of low- and intermediate mass (0.8‐8 M� ) in the final stage of evolution, moving between the asymptotic giant branch (AGB) stars and planetary

Proto-Planetary Nebulae

The progress in the search for proto-planetary nebulae (PPN) in the last 5 years is reviewed. An observational definition of PPN is developed and a list of current PPN candidates is given. The

Line identification and photometric observations of the future planetary nebula IRAS 18 062+2410=V886 Her in 1997–1999

AbstractPhotoelectric UBV observations of V886 Her in 1998–1999 have shown that the pattern of its variability is retained: irregular rapid light variations with an amplitude up to $$0\mathop

NEW VELOCIMETRY AND REVISED CARTOGRAPHY OF THE SPIRAL ARMS IN THE MILKY WAY—A CONSISTENT SYMBIOSIS

Recent advances in the determinations of the positions (pitch angle, shape, numbers, interarm separation) and velocities (rotation curve) of the spiral arms are evaluated and compared to previous
