Science, August 9, 2024.- A team of astronomers has discovered exoplanets orbiting their host stars, identified as TOI-6002 and TOI-5713, located 105 and 134 light-years from the Sun, respectively.
The new celestial bodies are named TOI-6002b and TOI-5713b and belong to the classification of ‘super-Earths‘.
A study published by the arXiv preprint service indicates that these exoplanets were detected through observations of the dimming of their light curves as they orbit their parent stars.
These data were collected using ground-based telescopes as well as the TESS space telescope from NASA.
For TOI-6002b, it is estimated to be four times more massive than Earth, with an orbital period of 10.9 days, placing it close to its parent star, at a distance of approximately 0.06 astronomical units (AU).
Additionally, it has a size nearly double that of our planet (1.65 Earth radii) and an equilibrium temperature of 47.95 degrees Celsius.
In contrast, TOI-5713b has a mass of 4.3 Earth masses, completing an orbit around its host star in 10.44 days, at a distance of 0.06 AU. Its size is equivalent to 1.77 Earth radii, and its equilibrium temperature is 74.05 degrees Celsius.
