I'm afraid I can't but you might get someone in sci.astro.research to give you a pointer to some data.

Light emitted from the photosphere of a star is definitely "near a large mass", more so than in a lab on Earth ! George

That range is at or beyond the limit for a useful parallax, even one measured by Hipparcos. With a reported standard error of 0.89 mas, the true distance could easily be anywhere from about two-thirds of that to double, although 600 LY seems on the low side. Googling for RT Aur's distance turns up numbers in the region of 400 pc. These are apparently based on the derivation of a distance modulus from the absolute magnitude, which in turn would have been calculated from the cepheid period-luminosity relation. At any rate a distance as small as 120 LY appears to be out of the question. -- Odysseus

Quite. If that's what it takes, such a star MUST exist. How can it not? Paul

I lost a factor of 2. I can never remember if the baseline is 1AU or 2AU.
