TL;DR: In this article, the authors presented the first study of six recently discovered Wolf-Rayet (WR) star clusters and found that they are real young (2-7 Myr) and massive (between 0.8 and 2.2 10^3 Msol) clusters.
Journal ArticleDOI
The Edge of the Milky Way Stellar Disk Revealed Using Clump Giant Stars as Distance Indicators
Dante Minniti,Dante Minniti,Roberto K. Saito,Javier Alonso-García,Philip W. Lucas,Maren Hempel +5 more
TL;DR: In this paper, the clump giants of the stellar disk of the Milky Way were used as standard candles calibrated from Hipparcos parallaxes in order to map their distribution with two near-IR surveys of the Galactic plane.
Journal ArticleDOI

TL;DR: In this paper, a new method for confirming transiting planets based on the combination of transit timingn variations (TTVs) and dynamical stability is presented, which provides evidence that the pair of bodies are in the same physical system.
Journal ArticleDOI
Parallaxes and physical properties of 11 mid-to-late T dwarfs

TL;DR: In this paper, the accuracy of model predictions in magnitude-color space, determine a magnitude-spectral type calibration, and estimate a bolometric luminosity and effective temperature range for the targets.
Journal ArticleDOI
Massive open star clusters using the VVV survey I. Presentation of the data and description of the approach
