The Outer Solar System Origins Survey (OSSOS) observations are acquired in blocks: contiguous patches of sky formed by a layout of adjoining multiple 0.90deg2 MegaCam fields. The OSSOS discovery and tracking program uses the Canada-France-Hawaii Telescope (CFHT) MegaPrime/MegaCam. This paper covers ...
Photometric and astrometric parameters of 14915 ultra-cool dwarf candidates found in Gaia DR2.
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006,. Both the spacecraft and the payload were built by European industry. The involvement of the scientific community focusses on data processing for which the ...
Gaia is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by ...
The database was aimed at providing stellar data for all observational types of double and multiple stars. This data base has been developped from 1996 to 2008 at Besançon Observatory. The project is now managed by the Institute of Astronomy of the Russian Academy of Science (INASAN) - see ...
Astrometric observations of TNOs obtained during the Canada-France Ecliptic Plane Survey (CFEPS), the High Latitude Survey (HiLat) and the Outer Solar System Origin Survey (OSSOS). Database also provides orbital information and dynamical classification, and future position predictions.
