Proper Motion of the Leo II Dwarf Galaxy Based On Hubble Space Telescope Imaging
Slawomir Piatek, Carlton Pryor, Edward W. Olszewski
This article reports a measurement of the proper motion of Leo II, a dwarf galaxy that is a likely satellite of the Milky Way, based on imaging with the Hubble Space Telescope and…
Proper Motion of the Draco Dwarf Galaxy Based On Hubble Space Telescope Imaging
Carlton Pryor, Slawomir Piatek, Edward W. Olszewski
We have measured the proper motion of the Draco dwarf galaxy using images at two epochs with a time baseline of about two years taken with the Hubble Space Telescope and the Advanc…
A Test for Radial Mixing Using Local Star Samples
Jincheng Yu, J. A. Sellwood, Carlton Pryor +2
We use samples of local main-sequence stars to show that the radial gradient of [Fe/H] in the thin disk of the Milky Way decreases with mean effective stellar temperature. Many of…
Velocity-space substructure from nearby RAVE and SDSS stars
Chang Hoon Hahn, J. A. Sellwood, Carlton Pryor
We extract a sample of disc stars within 200 pc of the Sun from the RAVE and SDSS surveys. Distances are estimated photometrically and proper motions are from ground-based data. We…
Proper Motions of the LMC and SMC: Reanalysis of Hubble Space Telescope Data
S. Piatek, C. Pryor, E. W. Olszewski
Kallivayalil et al. have used the \textit{Hubble Space Telescope} to measure proper motions of the LMC and SMC using images in 21 and five fields, respectively, all centered on kno…
Proper Motions of Dwarf Spheroidal Galaxies from Hubble Space Telescope Imaging. V: Final Measurement for Fornax
Slawomir Piatek, Carlton Pryor, Paul Bristow +5
The measured proper motion of Fornax, expressed in the equatorial coordinate system, is mas century. This proper motion is a weighted…
