Gaia and HST astrometry of the very massive 150 candidate runaway star VFTS682
M. Renzo, S. E. de Mink, D. J. Lennon +12
How very massive stars form is still an open question in astrophysics. VFTS682 is among the most massive stars known, with an inferred initial mass of 150 . It is l…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. XVI. The helium abundance of multiple populations
A. P. Milone, A. F. Marino, A. Renzini +16
Recent work, based on data from the Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GCs), has revealed that all the analyzed clusters host two groups o…
SMHASH: A new mid-infrared RR Lyrae distance determination for the Local Group dwarf spheroidal galaxy Sculptor
Alessia Garofalo, Victoria Scowcroft, Gisella Clementini +12
We present a new distance estimation for the Milky Way dwarf spheroidal satellite Sculptor obtained from multi-epoch mid-infrared observations of RR Lyrae stars. The 3.6 μm observa…
The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-Faint Galaxies
Nitya Kallivayalil, Laura Sales, Paul Zivick +7
According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-fai…
Evidence for an Intermediate-Mass Milky Way from Gaia DR2 Halo Globular Cluster Motions
Laura L. Watkins, Roeland P. van der Marel, Sangmo Tony Sohn +1
We estimate the mass of the Milky Way (MW) within 21.1 kpc using the kinematics of halo globular clusters (GCs) determined by Gaia. The second Gaia data release (DR2) contained a c…
SMASHing the LMC: A Tidally-induced Warp in the Outer LMC and a Large-scale Reddening Map
Yumi Choi, David L. Nidever, Knut Olsen +18
We present a study of the three-dimensional (3D) structure of the Large Magellanic Cloud (LMC) using ~2.2 million red clump (RC) stars selected from the Survey of the MAgellanic St…
