WASP-103 – an F-type Main-sequence Star

WASP-103 is an F-type main-sequence star in the constellation Hercules that is 1,800 100 light-years (550 ± 30 parsecs) distant. It has a surface temperature of 6,110±160 degrees Celsius (K). The concentration of heavy metals in the star is comparable to that of the Sun. WASP-103, at 4±1 billion years old, is somewhat younger than the Sun.

The star is too hot for starspots to form, thus its surface is covered by a swarm of dazzling faculae. The interaction with the massive planet in a close orbit raises the star’s chromospheric activity. In 2015, a multiplicity survey discovered a possible star companion to WASP-103 at an estimated separation of 0.242′′±0.016′′.

WASP-103 is located approximately 1532.9 light-years (470.0 pc) from our Solar System. WASP-103 has an apparent magnitude of 12.0 and an absolute magnitude of 3.6. It is 1.2 times more massive and 1.4 times larger than our Sun. The surface temperature is 6110 degrees Fahrenheit, and the spectral type is F8V. WASP-103 b radius is 1.528000 mass 1.490000 orbital distance 0.019850 is the name of one extrasolar planet.

Planetary system

The transit method detected one super-Jupiter planet, WASP-103b, in 2014. In less than a day, the planet will orbit its host star and may be near to the limit of tidal disruption. By 2020, no evidence of orbital degradation has been found. The planet gained popularity in early 2022 due to its potato-like shape.

WASP-103 b is a gas giant exoplanet in the habitable zone of an F-type star. It has a mass of 1.49 Jupiters, takes 0.9 days to complete one orbit of its star, and is located 0.01985 AU away from it. It was discovered in 2014, and its discovery was announced.

Water is present in the planetary atmosphere, as well as maybe hydrogen cyanide, titanium(II) oxide, or sodium. The planet has a high carbon to oxygen molar percentage of 0.9, implying that it is a carbon planet.

Cheops, the European Space Agency’s exoplanet project, discovered that an exoplanet orbiting its host star within a day has a distorted shape more resembling a rugby ball than a sphere. The planet, known as WASP-103b, is located in the Hercules constellation. The tremendous tidal pressures between the planet and its host star WASP-103, which is around 200 degrees hotter and 1.7 times larger than the Sun, have distorted it.

The planetary equilibrium temperature is 2,484±67 K, however there is a significant discrepancy between the night and day sides. The temperature during the day is 2,930±40 K, while the temperature at night is 1,880±40 K.
