The Astrophysical Journal, 2023 Our understanding of the kinematic properties of multiple stellar populations (mPOPs) in Galactic globular clusters (GCs) is still limited compared to what we know about their chemical and photometric characteristics. Such limitation arises from the lack

Corrections to the Hipparcos proper motions in declination for 807 stars [PDF]
Serbian Astronomical Journal, 2008 We used the data on latitude variations obtained from observations with 10 classical photographic zenith tubes (PZT) in order to improve the Hipparcos proper motions in declinations µδ for 807 stars.

Astrometry and Photometry for ≈1000 L, T, and Y Dwarfs from the UKIRT Hemisphere Survey
The Astronomical Journal, 2023 We present the positions, proper motions, and near-infrared photometry for 966 known objects with spectral types later than M that were observed as part of the the UKIRT Hemisphere Survey (UHS).

Walkaway Star Candidates in IC 348 and Their Possible Birthplaces
The Astrophysical Journal, 2023 Observations and theories reveal that star-forming regions eject their members during the early evolution of the cluster. We present an initial search for stars ejected from the young cluster IC 348 based on an analysis of Gaia EDR3 astrometry of ...

Evidence for a Massive Andromeda Galaxy Using Satellite Galaxy Proper Motions
The Astrophysical Journal, 2023 We present new mass estimates for Andromeda (M31) using the orbital angular momenta of four satellite galaxies (M33, NGC 185, NGC 147, and IC 10) derived from existing proper motions, distances, and line-of-sight velocities. We infer two masses for M31: $

Proper Motions of Water Masers in W49 N Measured by KaVA
The Astrophysical Journal, 2023 We report the proper motions of 22 GHz water masers toward W49 N that were observed by the KVN and VERA Array (KaVA) during 2017 February–May. We found 263, 268, and 310 features in three successive epochs; they were distributed in a region of size 4 × 4

Orbits of LMC/SMC with recent ground-based proper motions
EPJ Web of Conferences, 2012 In recent years, with new ground-based and HST measurements of proper motions of the Magellanic Clouds being published, a need of a reanalysis of possible orbital history has arisen.
