Photographic zenith tubes observations to improve HIPPARCOS proper motion in declination of some stars [PDF]
Serbian Astronomical Journal, 2005 A procedure of calculation and results of an attempt to improve proper motions in declination for some HIPPARCOS stars are presented. A long series of optical observations of these stars observed with Photographic Zenith Tubes (PZT) are used.

THE PROPER MOTION OF PALOMAR 5 [PDF]
The Astrophysical Journal, 2015 Palomar 5 (Pal 5) is a faint halo globular cluster associated with narrow tidal tails. It is a useful system to understand the process of tidal dissolution, as well as to constrain the potential of the Milky Way. A well-determined orbit for Pal 5 would enable detailed study of these open questions.

Position and Proper Motion of Sagittarius A* in the ICRF3 Frame from VLBI Absolute Astrometry
The Astronomical Journal, 2023 Sagittarius A* (Sgr A*) is a strong, compact radio source believed to be powered by a supermassive black hole at the galactic center. Extinction by dust and gas in the galactic plane prevents observing it optically, but its position and proper motion ...

Proper Motion of Solar Filaments [PDF]
Astronomy & Astrophysics, 1999 Precise measurements of heliographic position of solar filaments were used for describing the proper motion of solar filaments on the time-scale of one day. Only the velocity values more accurate than 100 m s−1 were used for the study. The filaments have a tendency to make a shaking or waving of the external structure and also to make a general ...

A 1500 deg2 near infrared proper motion catalogue from the UKIDSS Large Area Survey [PDF]
, 2013 The United Kingdom Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) began in 2005, with the start of the UKIDSS programme as a 7 year effort to survey roughly 4000 deg2 at high Galactic latitudes in Y, J, H and K bands.

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

A Technique To Derive Improved Proper Motions For Kepler Objects Of Interest [PDF]
, 2014 We outline an approach yielding proper motions with higher precision than exists in present catalogs for a sample of stars in the Kepler field. To increase proper-motion precision, we combine first-moment centroids of Kepler pixel data from a single ...

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.
