Absolute Magnitude Calibration for the W Uma - Typecontact Binary Stars
Hipparcos parallax data for 19 contact binary stars of the W UMa-type (with M V < 0:25) are used to check the previous absolute-magnitude calibration of the form M V = M V (log P; B ? V), and to derive a new one. The new calibration covers the ranges 1:7 < M V < 5:5, and gives practically identical predictions for M V as the previous one, although it is based on entirely independent M V data, w...
متن کاملAbsolute - Magnitude Calibration for W UMa - type Systems
A modiication to the absolute magnitude calibration for W UMa-type systems, taking into account diierences in metal abundances, is derived on the basis of contact binary systems recently discovered in metal-poor clusters. A preliminary estimate of the magnitude of the metallicity-dependent term for the (B V)-based calibration is M V = (0:3 0:1) F e=H]. The calibration based on the (V I C) color...
متن کاملAbsolute Magnitude Calibration for the W UMa-type Systems Based on Hipparcos Data
Hipparcos parallax data for 40 contact binary stars of the W UMa-type (with MV < 0.5) are used to derive a new, (B − V )-based absolute-magnitude calibration of the form MV = MV (logP, B − V ). The calibration covers the ranges 0.26 < (B − V )0 < 1.14, 0.24 < P < 1.15 day, and 1.4 < MV < 6.1; it is based on a solution weighted by relative errors in the parallaxes (2.7% to 24%). Previous calibra...
متن کاملThe Absolute Magnitude of Rr Lyrae
We derive the absolute magnitude of RR Lyrae stars by two independent maximum-likelihood estimations , using Hipparcos proper motion and par-allax data, respectively. By applying the statistical parallax method to 99 Halo RR Lyrae stars, we obtain the mean absolute magnitude < M V > = 0:69 0:10 at ={1.58. Independently of this method, we furthermore derive the M V { Fe/H] relation from H...
متن کاملA new absolute magnitude calibration with 2 MASS for cataclysmic variables
A new absolute magnitude calibration with 2MASS for cataclysmic variables Abstract Using reliable trigonometric measurements, we find that the absolute magnitude of cataclysmic variables depends on the orbital period and de-reddened (J − H) 0 and (H −K s) 0 colours of 2MASS (Two Micron All Sky Survey) photometric system. The calibration equation covers the ranges 0.032 d < P orb ≤ 0.454 d , −0....
