The Tycho-Gaia astrometric solution. How to get 2.5 million parallaxes with less than one year of Gaia data
Daniel Michalik, Lennart Lindegren, David Hobbs
Context. The first release of astrometric data from Gaia will contain the mean stellar positions and magnitudes from the first year of observations, and proper motions from the com…
Joint astrometric solution of Hipparcos and Gaia: A recipe for the Hundred Thousand Proper Motions project
Daniel Michalik, Lennart Lindegren, David Hobbs +1
The first release of astrometric data from Gaia is expected in 2016. It will contain the mean stellar positions and magnitudes from the first year of observations. For more than 10…
Improving distances to nearby bright stars: Combining astrometric data from Hipparcos, Nano-JASMINE and Gaia
Daniel Michalik, Lennart Lindegren, David Hobbs +2
Starting in 2013, Gaia will deliver highly accurate astrometric data, which eventually will supersede most other stellar catalogues in accuracy and completeness. It is, however, li…
