Astronomers observed the solar-type star HIP 104045 using the High Accuracy Radial Velocity Planet Searcher (HARPS) spectrograph on
The object was found using the Doppler method.It is also known as the radial or radial velocity method and is used to detect exoplanets. It consists of spectrometric measurement of the radial velocity of the star. A star with a planetary system will move in its own small orbit in response to the planet's gravity. Thanks to this method, more than 600 exoplanets have been discovered to date.
The minimum weight of HIP 104045 b isabout 0.5 Jupiter's mass and orbits its parent star every 2,315 days at a distance of about 3.46 astronomical units from it. As for HIP 104045 c, the mass of the object is at least 0.136 times the mass of Jupiter, and the orbital period is 316 days. This super-Neptune exoplanet is located approximately 0.92 AU from its parent star.
HIP 104045 is a relatively bright starmain sequence, it is almost as old as the Sun, but its size and mass are several percent greater than that of our star. Its effective temperature is 5826 Kelvin (5552.850 °C) and its age is estimated at 4.5 billion years.
Astronomers noted that HIP 104045 is very similar to the Sun in terms of its chemical content. They also suggest that the star may have swallowed up the rocky planet in the past.
