Abstract:
Planets in young star clusters could shed light on planet formation
and evolution since star clusters can provide accurate age estimation.
However, the number of transiting planets detected in clusters was
only ∼30, too small for statistical analysis. Thanks to the
unprecedented high-precision astrometric data provided by Gaia DR2 and
Gaia DR3, many new open clusters (OCs) and comoving groups have been
identified. The Understanding Planetary Formation and Evolution in
Star Clusters project aims to find observational evidence and
interpret how planets form and evolve in cluster environments. In this
work, we cross match the stellar catalogs of new OCs and comoving
groups with confirmed planets and candidates. We carefully remove
false positives and obtain the biggest catalog of planets in star
clusters up to now, which consists of 73 confirmed planets and 84
planet candidates. After age validation, we obtain the radius-age
diagram of these planets/candidates. We find an increment in the
fraction of hot Jupiters (HJs) around 100 Myr and attribute the
increment to the flyby-induced high-e migration in star clusters. An
additional small bump of the fraction of HJs after 1Gyr is detected,
which indicates the formation timescale of HJ around field stars is
much larger than that in star clusters. Thus, stellar environments
play important roles in the formation of HJs. The hot Neptune desert
occurs around 100Myr in our sample. A combination of photoevaporation
and high-e migration may sculpt the hot Neptune desert in clusters.
