A Catalog of Nearby Accelerating Star Candidates in Gaia DR3
The Astronomical Journal, 2023 We describe a new catalog of accelerating star candidates with Gaia G ≤ 17.5 mag and distances d ≤ 100 pc. Designated as the Gaia Nearby Accelerating Star Catalog (GNASC), it contains 29,684 members identified using a supervised machine-learning ...

USNO Bright Star Catalog, Version 1
The Astronomical Journal, 2022 Abstract The USNO Bright Star Catalog (UBSC) is a new astrometric catalog of the 1423 brightest stars covering the entire sky, which is published online. It is nearly complete to V = 3 mag except for three stellar systems. A combined astrometric solution of the Hipparcos Intermediate Astrometry Data and two dedicated ground-based ...

Precision Vs. Accuracy in Star Catalogs [PDF]
Symposium - International Astronomical Union, 1995 As better precision is achieved and more sophisticated reduction methods are created previously invisible biases surface. This has been especially true in astrometric Schmidt plate work. The problem of their amelioration is not fully solved and precision per se is meaningless in the presence of poor accuracy of comparable amplitude.

A Novel Inertial-Aided Star Pattern Matching Method for Distributed Multiple FoVs
International Journal of Aerospace Engineering, 2020 An aerospace vehicle in high-speed flight involves distributed multiple fields of view (FoVs) of a star sensor, and the maneuvering of the vehicle requires inertial-aided star pattern matching.

A Catalog Of Reference Stars For New Reductions Of The Astrographic Catalog Plates [PDF]
Symposium - International Astronomical Union, 1988 A high density reference star catalog is being compiled at the U. S. Naval Observatory for the purpose of making new reductions of the Astrographic Catalog. The catalog will be a replacement to the SAO catalog and will be derived from the large photographic catalogs and the modern meridian circle catalogs.

A Star Catalog for the Open Cluster NGC 188 [PDF]
Publications of the Astronomical Society of the Pacific, 2004 We present new BVRI broad-band photometry for the old open cluster NGC188 based upon analysis of 299 CCD images either obtained by us, donated by colleagues, or retrieved from public archives. We compare our results on a star-by-star basis with data from eleven previous photometric investigations of the cluster.

Redshift distribution of gamma-ray bursts and star formation rate [PDF]
, 2006 Aims. The redshift distribution of gamma-ray bursts collected in the BATSE Catalog is compared with the star formation rate.We aim to clarify the accordance between them. We also study the case of comoving number density of bursts monotonously increasing

Orbital Elements of visual binary stars with very short arcs: With application to double stars from the 1829 southern double star catalog of James Dunlop [PDF]
, 2022 Binary double stars are those whose binding energies are less than zero. Obtaining binary star orbits from short arcs has been a long-standing problem in astrophysics.
