J/AJ/127/2915   Triple systems (cool primary + hot binary)     (Parsons+, 2004)

New and confirmed triple systems with luminous cool primaries and hot companions Parsons S.B. <Astron. J., 127, 2915-2930 (2004)> =2004AJ....127.2915P
ADC_Keywords: Stars, double and multiple ; Ultraviolet ; Stars, supergiant ; Stars, late-type ; Photometry, UBVRI ; Photometry, infrared ; Parallaxes, trigonometric Keywords: binaries: general - stars: fundamental parameters - stars: late-type supergiants - ultraviolet: stars Abstract: In the course of comparing parameters of evolved cool star plus hot main-sequence star binaries with theoretical isochrones, some discrepancies are found between implied stellar masses and the spectroscopic binary mass function or the measured angular separation. These are naturally explained if there is a third star in the system. Multiplicity is also required to explain some comparisons of "cool plus hot binary" IUE and optical spectral energy distribution analysis with measured flux ratios, especially Tycho's two-color photometry of separate components. Out of a sample of 136 cool-plus-hot binary star systems under study, measurements are now indicating several systems considered double (HD 5373, 23089, 26673, 29094, 49126, 71129, 149379, 179002, 187299), and probably a few others (including HD 136415), to have at least three stellar components. Several other cases of suspected triple systems are confirmed. For comparison, there are eight known triples included in the project. In all, about 25% of the systems contain three or more components within a few arcseconds. Estimated separations are provided, which may be of use when not known from interferometry. In general, the triple systems have one post-main-sequence component and two upper main-sequence components, usually revolving around each other. One new triple system, HD 149379, has as its middle component an F giant in the brief first crossing of the Hertzsprung gap. File Summary:

Note (1): Specifies the component, or the pairing when a slash ("/") is used. The nomenclature system for components uses the scheme of the Washington Multiplicity Catalog. Note (2): Note on log(Teff), as follows: adj = Component masses are adjusted relatively little; alt = There is a plausible alternative fit to isochrone; 2m = The secondary's mass is multiplied by 2 (for example). Note (3): Initially for each system the DelV from SED analysis (section 3.1). It is the magnitude difference between the (first) component on the line directly beneath its value and the component on the same line. For multiple systems' data from external sources, though, DelV refers to the two components that are separated by a slash on the same line as the value. Note (4): Sometimes two fits, with and without using a loop, are reported here with one given as an alternative fit, as follows: n = Primary component not on a blue loop y = Primary component falls on a blue loop (y = Blue loop is slightly extrapolated ((y = Blue loop is significantly extrapolated tip = Near the maximum red giant expansion y* = Between the tip and the minimum visual luminosity along the loop y+ = Placed at an evolutionary phase beyond the maximum temperature phase of the loop XX = No isochrone fit is possible Note (5): Notes on Mass, as follows: N = See note in notes.dat file. XX = No isochrone fit is possible. Note (6): Or the external value from Hipparcos. In the latter case, a colon denotes a standard deviation in the range 20%-39% of the parallax value; a double colon, σ in the range 40%-59%; and parentheses, σ in the range 60%-79%. Note (7): the tilde (~) indicates a measured separation for a recent epoch, not an orbital determination or estimate of the semimajor axis. Note (8): The period values, though taken from external sources, are not repeated on the external lines unless needed for clarity. When there is no spectroscopic period, Per may contain an eclipse light-curve period followed by "L", an astrometric period followed by ")", or a value calculated from an external separation value and Kepler's third law followed by "]".
