  author={Maria Messineo and A. G. A. Brown},
  journal={The Astronomical Journal},
We investigate individual distances and luminosities of a sample of 889 nearby candidate red supergiants (RSGs) with reliable parallaxes (ϖ/σϖ > 4 and RUWE < 2.7) from Gaia Data Release 2 (DR2). The sample was extracted from the historical compilation of spectroscopically derived spectral types by Skiff, and consists of K-M stars that are listed with class I at least once. The sample includes well-known RSGs from Humphreys, Elias et al., Jura & Kleinmann, and Levesque et al. Infrared and… 

Evolved massive stars at low-metallicity

We present a case study in which we used a novel method to identify red supergiant (RSG) candidates in NGC 6822 based on their 1.6 μm H-bump. We collected 32 bands of photometric data for NGC 6822

An infrared study of Galactic OH/IR stars – III. Variability properties of the Arecibo sample

We present the results of a near-infrared (NIR) monitoring program carried out between 1999 and 2005 to determine the variability properties of the ‘Arecibo sample of OH/IR stars’. The sample

Red Supergiants in M31 and M33. I. The Complete Sample

The aim of this paper is to establish a complete sample of red supergiants (RSGs) in M31 and M33. The member stars of the two galaxies are selected from the near-infrared (NIR) point sources after

Massive Stars in Molecular Clouds Rich in High-energy Sources: The Bridge of G332.809–0.132 and CS 78 in NGC 6334

Detections of massive stars in the direction of the H ii region CS 78 in NGC 6334 and of G332.809−0.132 are here presented. The region covered by the G332.809−0.132 complex coincides with the RCW 103

New Infrared Spectral Indices of Luminous Cold Stars: From Early K to M Types

We present infrared spectral indices (1.0–2.3 μm) of Galactic late-type giants and red supergiants (RSGs). We used existing and new spectra obtained at resolution power R = 2000 with SpeX on the IRTF

Time-series photometry in the I and J bands of 57 inner Galactic late-type stars, highly probable red supergiant (RSG) stars, is presented here. 38% of the sample presents significant photometric

The K supergiant runaway star HD 137071

Context. Extensive work exists on runaway massive stars with peculiar motions that are much higher than those typical of the extreme Population I to which they belong. Work on runaways has focused

Abstract I would like to present an overview of red supergiants (RSGs) in the Milky Way. There are only about 1400 objects listed as RSGs in the spectroscopic catalog by Skiff (2014); moreover, we

Digitization, Measurement, and Analysis of a 1905 Barnard Atlas Photographic Plate

In the second paper in this series, we improve on our previous demonstration of the ability of a commercially available graphic arts scanner and cost-effective analysis tools to produce



Red Supergiants in the Inner Galaxy: Stellar Properties

Red supergiants (RSGs) are luminous cool stars detectable in disks of distant spirals. About a thousand are known in the Galaxy. Here, we analyze a sample of late-type stars recently observed by


In this Letter, we present a search for Galactic red supergiant stars (RSGs) in the direction of the inner Galaxy. A total of 94 targets selected from the 2MASS and GLIMPSE I North catalogs—via their

The Cool Supergiant Population of the Massive Young Star Cluster RSGC1

We present new high-resolution near-IR spectroscopy and OH maser observations to investigate the population of cool luminous stars of the young massive Galactic cluster RSGC1. Using the 2.293 μm CO

86 GHz SiO maser survey of late-type stars in the Inner Galaxy

We present an 86 GHz SiO (v = 1,  J = 2 → 1) maser search toward late-type stars located within |b|< 0.​​°5 and 20° <  l <  50°. This search is an extension at longer longitudes of a previously

The Lack of Blue Supergiants in NGC 7419, a Red Supergiant-rich Galactic Open Cluster with Rapidly Rotating Stars

According to previous studies based on photometry alone, NGC 7419 reveals a surprisingly low ratio of blue to red supergiants: only one blue supergiant (BSG) along with a record number of five red


We present Hubble Space Telescope/Near-Infrared Camera and Multi-Object Spectrometer photometry, and low-resolution K-band spectra of the GLIMPSE9 stellar cluster. The newly obtained color–magnitude

A search for late-type supergiants in the inner regions of the Milky Way

We present the results of a narrow-band infrared imaging survey of a narrow strip (12 � wide) around the Galactic equator between 6 ◦ and 21 ◦ of galactic longitude aimed at detecting field stars

A New Infrared Array Photometric Survey of Galactic Globular Clusters: A Detailed Study of the Red Giant Branch Sequence as a Step toward the Global Testing of Stellar Models

We present high-quality near-infrared color-magnitude diagrams of 10 Galactic globular clusters (GCs) spanning a wide metallicity range (-2.15 < [Fe/H] < -0.2). This homogeneous database has been

SiO maser emission from red supergiants across the Galaxy - I. Targets in massive star clusters

Aims. Red supergiants (RSGs) are among the most luminous of all stars, easily detectable in external galaxies, and may ideally serve as kinematic tracers of Galactic structure. Some RSGs are

Near-infrared spectroscopy of candidate red supergiant stars in clusters

Clear identifications of Galactic young stellar clusters farther than a few kpc from the Sun are rare, despite the large number of candidate clusters. We aim to improve the selection of candidate
