Table information for 'basecom.epn_core'


Table Description: plasma in planetary atmosphere.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: Since 1973, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nançay radio telescope. This allowed an evaluation of the cometary water production rates and their evolution with time, as well as a study of several physical processes: the excitation mechanisms of the OH radio lines, the expansion of the cometary atmospheres, their anisotropy in relation with non-gravitational forces, the Zeeman effect in relation with the cometary magnetic field. The Nançay observations of 53 cometary apparitions between 1982 and 2009 are now organized in this database.

Citing this table

This table has an associated publication. If you use data from it, it may be appropriate to reference 2010Icar..205..559V (ADS BibTeX entry for the publication) either in addition to or instead of the service reference.

To cite the table as such, we suggest the following BibTeX entry:

  title={The Nançay Cometary Databa},
  author={Observatoire de Paris - {LESIA}},
