Abstract:
This catalogue contains compilations of observable data for 176
massive close binaries with components earlier than approximately B5
of the main sequence are presented.
Description:
A catalogue of massive close binaries with early-type components of
the main sequence was created. This catalogue includes physical,
geometrical and evolution characteristics of these objects, spectral
and photometrical pecularities and orbital features. The aim of this
work was to research observational phenomena of gas presence around
these binaries. The catalogue also contains data on radio and X-ray
observations. The catalogue can be used for the creation of
observational programmes, for analysis and interpretation of the
binary star observational data and for statistical investigations. It
contains information extracted from the database of Galactic massive
close binaries (M>10M☉) with early type components. This
database is compiled from the General Catalogue of Variable Stars
(GCVS) (Kholopov et al., 1985, Cat. B/gcvs), the eighth catalogue of
the orbital elements of spectroscopic binary systems (Batten et al.,
1989, Cat. V/64), and the Sternberg Astronomical Institute card
catalogue of variable stars and current original publications. It
excludes O(f), O((f)) and WR stars and systems with relativistic
objects.
The current sample includes 176 close binaries earlier than about B5.
The results of systematization are in two tables.
Table 1 contains the sample list of massive close binaries with their
basic data. 74 of these systems have been the subject of some spectral
observations and some observations of light curves; therefore the
absolute parameters of these systems may be determined.
Table 2 consists of massive close binaries with early-type components
of the main-sequence catalogue, which consists of these 74 systems.
They are grouped in the following configurations: detached
main-sequence systems, semidetached main-sequence systems, contact
systems, four groups which are combinations of these, and finally
giant and supergiant systems. All variables in the present data set in
Tables 1 and 2 are arranged in the order of their names inside
constellations. Greek or Latin adopted star names before variability
was discovered and the very well known are arranged at the end of the
list. The full electronic version of this catalogue consists of two
databases. One of these is the database of observational data and of
the results of theoretical analysis. The other database includes the
individual bibliography and abstracts to data sources for each binary.

Note (1): Type of system is marked by number as follows:
1 = Detached Main Sequence Systems
2 = Semidetached Main Sequence Systems
3 = Contact systems
4 = Detached Main Sequence - Semidetached Main Sequence Systems
5 = Detached Main Sequence - Contact systems
6 = Semidetached Main Sequence - Contact systems
7 = Detached Main Sequence - Semidetached Main Sequence - Contact Systems
8 = Giant and Supergiant Systems
Note (2): types of light curve are as follows:
EA = Algol-type light curve
EB = β Lyrae-type light curve
Ell = binary systems, whose variability is caused by ellipsoidal shapes
EW = W UMa-type light curve
Note (3): The spectral type and component masses are according to the latest
investigation employing spectral and photometry observations.
Note (4): The spectral parameters obtained by different researchers are
highly discrepant for many systems which are marked by [:]. The spectral
types of some systems vary with phase of period.
Note (5): Some stars in the catalogue have masses M<10M☉. This may
accounts for the large spread in mass estimates obtained by different
researchers.
Note (6): The flag of uncertainty [:] indicates large differences in mass
estimates, by a factor of more than 2.
Note (7): Separation between object and visual components.
