Section 3.6 Selected Stars from the Hipparcos
Section 3.6 Selected Stars from the Hipparcos Catalogue 481 3.6. Selected Stars from the Hipparcos Catalogue In this section certain key results from the Hipparcos Catalogue are presented for various sets of stars selected according to a number of criteria. Table 3.6.1 lists results for the 150 stars closest to the Sun, as deduced from the Hipparcos parallaxes. No criterion was applied to the precision of the individual parallax determinations. The entries in the table are sorted by decreasing parallax (increasing distance). Table 3.6.2 gives the results for the 150 stars with the largest total proper motions in the Hipparcos Catalogue, again without further selection on precision. Table 3.6.3 gives the results for the 150 stars with the largest total transverse velocity, as deduced from the Hipparcos proper motions and parallaxes. In the latter table, only stars with relative distance precision σπ /π < 0.1 were included. The entries in these tables are sorted by decreasing total proper motion and total transverse velocity, respectively. For Table 3.6.4, the table with 150 stars with the highest absolute luminosity, the se- lection was more delicate. Although Hipparcos has determined for each entry at least a lower limit for the distance, and consequently for the luminosity, the inclusion of stars with only such a lower limit in the table was not considered meaningful. The stars in the table meet the two following criteria: (i) relative distance precision σπ /π < 0.3; (ii) ab- solute magnitude MV when computed with the 2-σ lower distance limit 1/(π + 2σπ ) smaller than −2 mag. -
