Geminga underwent a minor glitch in the late part of 1996, with a fractional change in frequency of 6.2 × 10 −10. [17]A 1998 study of the pre-glitch ephemeris suggested that the timings were being affected by reflex motion due to the presence of a low-mass planet in a 5.1-year orbit; [18] however, this was later shown to be an artifact of noise that affects the pulse times from Geminga ...
TV Geminorum (TV Gem / HD 42475 / HR 2190) is a variable red supergiant in the constellation Gemini. Its visual magnitude varies from 6.3 to 7.5, making it very faintly visible to the naked eye of an observer with excellent observing conditions, when the star is near its peak brightness.
Epsilon Geminorum or ε Geminorum, formally named Mebsuta / m ɛ b ˈ s uː t ə /, [11] [12] is a star in the constellation of Gemini, on the outstretched right 'leg' of the twin Castor. The apparent visual magnitude of +3.06 [2] makes it one of the brighter stars in this constellation. The distance to this star is determined at 860 light ...
η Gem is the bright star lying just outside the supernova remnant IC 443 (WISE infrared image) η Geminorum is a triple system, with the luminous class M star having a close companion known only from radial velocity variations, and a more distant companion resolved visually. In 1881, Burnham observed that η Geminorum had a close companion (η ...
Theta Geminorum (θ Gem, θ Geminorum) is a single [11] star in the northern zodiac constellation of Gemini. It is visual to the naked eye with an apparent visual magnitude of 3.59. [ 2 ] Based upon an annual parallax shift of 17.25 mas , [ 1 ] it is about 189 light years distant from the Sun .
Mu Geminorum or μ Geminorum, formally named Tejat (/ ˈ t iː dʒ ə t /), [14] is a single star in the northern/tropical constellation of Gemini which can be seen from all but Antarctic latitudes. From parallax measurements obtained during the Hipparcos mission, it is roughly 230 light-years (71 parsecs ) distant from the Sun . [ 1 ]
Wasat is the bright star next to Jupiter. [17] Jupiter is ~280× brighter. Delta Geminorum is a subgiant star with the stellar classification F0 IV. [3] It is about 60.5 light-years (18.5 parsecs) distant. [1] This star has 1.57 times the mass of the Sun [6] and is rotating rapidly with a projected rotational velocity of 129.7 km s −1. [8]
It is an evolved giant star of the spectral type K2 III. It has double [ 6 ] the mass of the Sun and has expanded to 30 times the Sun's radius. Tau Geminorum is radiating 364 [ 4 ] times as much radiation as the Sun from its expanded outer atmosphere at an effective temperature of 4,583 K, [ 4 ] giving it the characteristic orange-hued glow of ...
