Parameters for the Eclipsing B - star Binary HD 42401
I present results from an optical spectroscopic investigation of the binary system HD 42401 (V1388 Ori; B2.5 IV-V + B3 V). A combined analysis of V−band photometry and radial velocities indicates that the system has an orbital period of 2.18706 ± 0.00005 days and an inclination of 75.5 ± 0.2 degrees. This solution yields masses and radii of M1 = 7.42 ± 0.08 M⊙ and R1 = 5.60 ± 0.04 R⊙ for the pr...
متن کاملA young and complex binary star - HD 144432
The southern emission-line star HD 144432 has received considerable attention due to its relative brightness (V ∼ 8.17), its late spectral type (late A-type or perhaps early F) and its relative isolation from a bona-fide active star formation region. We present new imaging and spectroscopic data of this star, which in the past has been classified as both evolved (post-AGB) object and an isolate...
متن کاملAn electrically powered binary star?
We propose a model for stellar binary systems consisting of a magnetic and a non-magnetic white-dwarf pair which is powered principally by electrical energy. In our model the luminosity is caused by resistive heating of the stellar atmospheres due to induced currents driven within the binary. This process is reminiscent of the Jupiter-Io system, but greatly increased in power because of the lar...

متن کاملPixel Scale and Orientation of Pharo Determined from the Binary Star HD 165341
The binary star HD 165341 was observed with the Palomar 200-inch telescope using Pharo + AO at the f/29.91 focal ratio on 2002 Jun 23 for the purposes of determining the plate scale and the location along the cass ring of true north. HD 165341, a bright (V=4 mag) 4. 55 binary, has an accurately determined orbit (grade 1) with orbital parameters listed in both Pourbaix (2000, A&AS, 145, 215) and...
