The fourth edition of the Bright Star Catalogue is an updated and improved version of the previous edition published in 1964 by the same author. In addition to the large number of newly determined fundamental data, such as photoelectric magnitudes, MK spectral types, parallaxes, and radial velocities, the new version contains new data and information not included in the third edition. Valuable information, such as the identification of IR sources, U-B and R-I colors, radial velocity comments (indication and identification of spectroscopic and occultation binaries), and projected rotational velocities, is included for the first time in the fourth addition, while the equatorial coordinates for equinoxes B1900.0 and J2000.0 are recorded to greater precision (0.1s in right ascension, 1" in declination).

The remarks section presented in the file BSC4.REM, has been expanded and improved to contain many details concerning variability, spectral characteristics, duplicity, and group membership, and the remarks have been segregated by category to improve information retrieval and readability (see note 12 and appendix 1). The catalogue in general contains data compiled through 1979; however, some information and variable-star designations found through 1981 are included in the remarks and many variable-star names have subsequently been transferred to the data file.

As in previous editions of this catalogue, the only stars included are those having HR numbers (Pickering 1908). The ostensible visual magnitude limit of the HR catalogue was 6.50 and it contains 9,110 objects. The two previous editions (1940 and 1964) omitted 19 stars so that the number of stars tabulated was 9,091, although the last star number is always 9,110. In the catalogue are also present 9 novae or supernovae (NOVA 1903, 1572, 1891, 1901, 1848, 1670, 1876, 1604, 1899), 4 globular clusters (47 TUC, NGC2281, M67, NGC2808) and the Andromeda galaxy (M31 AND), whose records are blank except for HR number, NAME and sometimes variable-star designations, and are listed at the beginning of the file. These objects were included in the first edition of the catalogue and omitted in subsequent editions (the records are retained in order to preserve the numbering of the first catalogue).

NOTES

12*.

A vast amount of information on the bright stars could not readily be included in the catalogue proper, partly because of space limitations, but mainly because of the different nature of many of the notes. All of this material is collected in the file BSC4.REM (containing 7,959 records relative to 4,278 BS stars) according to the following format and it is divided into the categories explained in appendix 1:

- Variables number 3 - Records number 7959 - Record length 132 -

Code Col. Format Description
HR 2 I4 HR = BS number.
CATEGORY 8 A4 A 1-3 letter remark category abbreviation, followed by a colon (:). See appendix 1 for explanation.
REMARK 13 A120 Remark in free form text. See table 1.

To aid the user in a correct reading of this file, it is important to take into account the following cases, for which it was not possible to treat the above file as a DIRA catalogue:

  1. non-blank HR field indicates the start of a remark for a new star,

  2. blank HR and non-blank CATEGORY fields indicate the start of a remark for the previous star in a new category,

  3. blank HR and CATEGORY fields  indicate the continuation of the remark for the previous star and category.

*

The notes from 1 to 11 refer to DIRA2 catalogue format, now under construction.

APPENDICES

1. Explanation of remark categories

N

Star Names and identifications. Often more than one name is given for a particular star. Preference is to be given to the name as it appears in Norton's Star Atlas (17th ed., 1978), indicated here by having all of the letters of the name capitalized.

C

Colors, including color excess and remarks on IR sources.

S

Spectra. Notes on discordances in classification, peculiarities, etc...

VAR

Variable stars. Most of the notes in this category comprise types of variability, maximum and minimum magnitudes, and periods. Notes are also included in this category for stars not known to show variability in light, but which have shown changes in spectrum, magnetic field, or other characteristics (unless such changes are noted under S, SB, RV or D).

SB

Spectroscopic Binaries. Mostly orbital data:

-

the period of revolution;

-

K, the half amplitude of the radial velocity in the orbiting system, or K1 and K2, the semi-amplitude in RV for each of the components of a double-lined spectroscopic binary;

-

V0, the mean radial velocity of the system;

-

msin³i, the mass function in terms of the solar mass;

-

asini, the projected semi-major axis in units of 106 km. 

If the period is followed by the letter A or D, the period was derived from astrometric or visual double star data, respectively, not from the radial velocities.

RV

Radial and Rotational Velocities, v·sini. Frequently such data for the secondary components of visual or multiple stars are shown, but not data already included under SB or D.

D

Double and multiple stars, including astrometric (indicated by *) and those discovered by occultations or speckle interferometry. Orbital data are given, including magnitudes and spectral classes of the major components, orbital periods, and semi-major axes, a. (Where magnitudes are given without specifying the color, visual v is meant).

DYN

Dynamic parallaxes. None from literature prior to 1962.

R

Stellar Radii or diameters.

P

Polarization.

G

Membership in cluster, groups, associations, and apparent association with nebulosity (R associations). Conflicting assignments in different sources are not necessarily resolved: the various alternatives are included.

M

Miscellaneous notes.
