Stellar Absolute Magnitudes via the Statistical Parallax Method
I review statistical parallax absolute magnitude determinations which employ data from the Hipparcos satellite for RR Lyrae and Cepheid variables, and for several other stellar classes. Five groups have studied the RR Lyrae stars, and the results are reassuringly consistent: MV (RR) = 0.77 ± 0.13 mag at [Fe/H] = –1.6 dex. Extensive Monte Carlo simulations showed that systematic errors are small...
متن کاملRelativistic stellar aberration for the Space Interferometry Mission: parallax analysis
This paper is a continuation of our previous analysis (i.e. Turyshev 2002a, 2002b) of the relativistic stellar aberration requirements for the Space Interferometry Mission (SIM). Here we have considered a problem of how the expected astrometric accuracy of parallax determination will constrain the accuracy of the spacecraft navigation. We show that effect of the spacecraft’s navigational errors...
متن کاملPrimitive Parallax and Parallax Primitives
This paper describes an implementation of parallax depth perception designed to be a contributing unit to a distributed perceptual intelligence. The work was done in the context of the Cog project, a large-scale eeort to develop human or at least infant intelligence from the bottom up. Our implementation uses fast-approximation \good enough" region mapping and relevant motion detection over mul...
متن کاملA Redetermination of the Mass of Procyon
The parallax and astrometric orbit of Procyon have been redetermined from PDS measurements of over 250 photographic plates spanning 83 years, with roughly 600 exposures used in the solution. These data are combined with two modern measurements of the primaryÈwhite dwarf separation, one utilizing a ground-based coronagraph, the other, the Planetary Camera (PC) of the Hubble Space Telescope. Toge...
