HIP 79431 – a Red Dwarf Star

HIP 79431 – a Red Dwarf Star

In the constellation Scorpius, HIP 79431 is a red dwarf star with a non-stellar partner. This star is around 47.8 light-years (14.6 pc) from our Solar System. It was given the proper name Sharjah as part of the United Arab Emirates’ NameExoWorlds campaign to commemorate the IAU’s 100th anniversary. The cultural capital of the United Arab Emirates is Sharjah. This star is smaller, cooler, dimmer, and has a lower mass than our Sun. It also has 2.5 times the metal concentration of the Sun.

It is 0.5 times more massive and 0.5 times larger than our Sun. The star’s apparent visual magnitude is 11.34, making it far too faint to be seen with the naked eye. The surface temperature is 3191 degrees Fahrenheit, and the spectral type is M3V. Based on parallax data, this system is 47.4 light-years away from the Sun. With a radial velocity of 5 km/s, it is getting closer.

HIP 79431 has an apparent magnitude of 11.3, and an absolute magnitude of 10.5. M3V is the stellar classification of this M-type main-sequence star. This star is smaller, cooler, dimmer, and less massive than our Sun, but its metal concentration is predicted to be 2.5 times that of the Sun. The level of chromospheric activity does not appear to be out of the ordinary for a star of this caliber.

HIP 79431 b has a radius of 0.907830, a mass of 2.100000, and an orbital distance of 0.360000. The W. M. Keck Observatory identified HIP 79431 b, an extrasolar planet, in 2010. The planet is discovered in an M-type dwarf star known as HIP 79431, which is located in the Scorpius constellation and is roughly 47 light-years away from Earth. It has an orbital period of roughly 111.7 days and an eccentricity of 0.29. A superjovian planet was discovered in orbit around the star in 2010. This planet is one of the largest discovered in the vicinity of a red dwarf star. This planet is one of the largest discovered in the vicinity of a red dwarf star. The planet is the sixth big planet discovered in M dwarf Doppler surveys and is thought to be one of the most massive planets discovered near M dwarf stars.

HIP 79431 is an 11th magnitude M-type main-sequence star found in the constellation Scorpius around 47 light-years distant. Using the radial-velocity approach, a super jovian exoplanetary partner was identified in 2010. It orbits the hos star at a distance of 0.36 AU, with a period of 0.3 years and an eccentricity (ovalness) of 0.29. Because the orbit’s inclination is uncertain, only a lower constraint on the mass can be computed. It has at least 2.1 times the mass of Jupiter.
