Interferometry from Space: A Great Dream
Erik Høg
During some thirty years, 1980-2010, technical studies of optical interferometry from instruments in space were pursued as promising for higher spatial resolution and for higher as…
Exo-Jupiters and Saturns from two Gaia-like missions
Erik Høg
Detection and orbit determination for thousands of planets with periods up to about 40 years would be obtained by astrometry from two Gaia-like missions, results which cannot be ob…
A Gaia successor with NIR Sensors
Erik Høg, Jens Knude
The expected accurate astrometric data from Gaia offer the opportunity and the obligation to exploitation by a second all-sky mission. Therefore a proposal was submitted to ESA in…
Astrometry for Dynamics
Erik Høg
In May 2013, I responded with the present paper to ESA's call for White Papers for the definition of Large missions. This was half a year before the launch of ESA's large astrometr…
Astrometry 1960-80: from Hamburg to Hipparcos
Erik Høg
Astrometry, the most ancient branch of astronomy, was facing extinction during much of the 20th century in the competition with astrophysics. The revival of astrometry came with th…
Solar system and small-field astrometry
Erik Høg, George Kaplan
Astrometric issues for solar system studies are discussed. An overview gives references and cover all aspects of the solar system where astrometry is important: orbits of planets,…
