It forms one of the four feet of the outline demarcating the Gemini twins. The temperature was calculated using information from Morgans @ Uni.edu. A technique called photometry reveals a star’s temperature by measuring its color. Intercomparison of occultation data from various observatories shows poor correlation of the raw data but apparent correlations in the derived temperature profiles, as discussed in a paper by French and Elliott. And astronomers get a star’s true brightness by comparing its distance to how bright it looks in the night sky. The past 10-plus stars were, for:

Mu Geminorum (μ Geminorum, abbreviated Mu Gem, μ Gem), formally named Tejat / ˈ t iː dʒ ə t /, is a single star in the northern constellation of Gemini. Its name is Latin for the twins and it's one of the few constellations in the sky that actually looks like what it suppose to represent. III - Temperature structure of the Martian upper atmosphere III - Temperature structure of the Martian upper atmosphere Authors: French, R. … Castor is also not the brightest star in Gemini; that honor goes to neighboring Pollux. Due to illness, the star was delayed a week. The new stars, for September 29, 2017, are XI-1 and XI-2 SGR (Xi-1 and Xi-2 Sagittarii), two massive unrelated stars, one in rapid evolution, tied together by being in the same minor asterism. Within the altitude range 50-80 km above the mean surface, the mean temperature is about 145 K, and the profiles exhibit wavelike structures with a peak-to-peak amplitude of 35 K and a vertical scale of about 20 km. IUE UV spectra of Epsilon Gem and Alpha Ori show no evidence of emission lines formed at temperatures greater than 10,000 K, leading to the computation of chromospheric models extending to 10 to the -6th g/sq cm at temperatures that rise to 6500 K for the former star and 7000 K for the latter. For CO 2 gas, this result corresponds to a temperature of 190 + or - 50 K. An analysis of observations of the occultation of Epsilon Gem by Mars on April 8, 1976, is presented. The star has an apparent visual magnitude of 3.35, which is bright enough for it to be seen with the naked eye. Gemini is a northern zodiac constellation and one of the 48 constellations described by second century astronomer Ptolemy. Temperature is indicated as the effective surface temperature divided into 50400 and rounded to the first decimal place, e.g. Title: Occultation of Epsilon Geminorum by Mars. From stellar parallax measurements, its distance from the Sun can be estimated as 58.7 light-years. the next star will appear October 13. Epsilon Geminorum is yellow-orange, so it’s fairly cool. Temperature profiles are derived by numerical inversion of the star's light curves and found to be in mutual agreement.
