These planets are two of the most promising candidates for follow-up studies. James Webb Space Telescope, are you listening?
The desire to find Earth-like planets led to the development of the Search for habitable Planets EClipsing ULtra-cOOl Stars It’s a project at the European Southern Observatory’s Paranal Observatory in Chile. SPECULOOS is a survey of about 1700 M dwarfs using the transit method to spot planets similar to Earth.
The planet closest to the star, LP 890-9 b, is about 30% larger than Earth, has an orbital period of 2.73 days and is 0.019 au away from the star. The second planet, LP 890-9 c, is slightly larger than the first planet, takes longer to orbit with a period of 8.46 days and is 0.040 au from the star. That means that both planets fit well inside Mercury’s orbit around the Sun for comparison.
Although this planet orbits very close to its star, at a distance about 10 times shorter than that of Mercury around our Sun, the amount of stellar irradiation it receives is still low and could allow the presence of liquid water on the planet’s surface, provided it has a sufficient atmosphere,This is because the star LP 890-9 is about 6.5 times smaller than the Sun and has a surface temperature half that of our star.
How do these planets compare to other exoplanets around cool dwarf stars? The team plotted them on a chart with other exoplanets around similar stars found in NASA’s Exoplanet Archive. They restricted the data to planets around stars with a surface temperature lower than 3600 Kelvin.
