The Hipparcos Transit Data : What , why and how ? ?

Astronomy and Astrophysics the Hipparcos Transit Data: What, Why and How?

The Hipparcos Transit Data are a collection of partially reduced, fully calibrated observations of (mostly) double and multiple stars obtained with the ESA Hipparcos astrometry satellite. The data are publicly available, as part of the CD-ROM set distributed with the Hipparcos and Tycho Catalogues (ESA SP–1200, 1997), for about a third of the Hipparcos Catalogue entries including all confirmed ...

The Why, Who, What, How, and When of Patient Engagement in Healthcare Organizations: A Response to Recent Commentaries

Detection of Planetary Transits of the Star HD 209458 in the Hipparcos Data Set.

A search of the Hipparcos satellite photometry data for the star HD 209458 reveals evidence for a planetary transit signature consistent with the planetary properties reported by Henry et al. and Charbonneau et al. and allows further refinement of the planet's orbital period. The long time baseline (about 2926 days or 830 periods) from the best Hipparcos transit-like event to the latest transit...

Aging, Pensions and Long-term Care: What, Why, Who, How?; Comment on “Financing Long-term Care: Lessons From Japan”

Japan has been aging faster than other industrialized nations, and its experience offers useful lessons to others. Japan has been willing to expand its welfare state with a long-term care (LTC) insurance to finance home care and nursing home care for frail elderly. As Ikegami shows, it created new facilities and expanded specialized staffing for home care, developed a c...

Re - processing the Hipparcos Transit Data and Intermediate

Only 235 entries were processed as astrometric binaries with orbits in the Hipparcos and Tycho Catalogue (ESA 1997). However, the Intermediate Astrometric Data (IAD) and Transit Data (TD) made available by ESA make it possible to re-process the stars that turned out to be spectroscopic binaries after the completion of the Catalogue. This paper illustrates how TD and IAD may be used in conjuncti...
