Description
North PHASE survey is a 5 year survey that will be using time-resolved, large field data, to unveil structures and processes in young stars (YSO) at the relevant scales for inner planet formation, while also studying the connection between stars, their formation history, and their clusters, independently of astrometry.
Studying young star cluster Trumpler 37 (Tr37) provides key insights into star formation, protoplanetary disk evolution, and stellar feedback mechanisms from local to galactic scales. Tr37, a 4 Myr old cluster contains a diverse population, including massive OB stars and low-mass T Tauri stars. This makes it an ideal laboratory for examining early stellar evolution and the role of cluster environments in shaping star formation outcomes.
Tr37 hosts numerous stars with circumstellar disks, including classical T Tauri stars and transition disk objects, allowing the study planet-forming processes and disk dissipation mechanisms. The presence of massive stars in Tr37 significantly influences its surroundings through intense UV radiation and stellar winds, leading to photoevaporation of disks and triggered star formation in nearby gas clouds.
Additionally, Tr37 exhibits subclustering, providing a natural setting to investigate cluster dynamics and eventual dispersion into the galactic field population. Observing Tr37 helps bridge the gap between local star formation studies and large-scale galactic evolution, offering a framework for understanding star formation in distant starburst regions and galaxies. By analyzing clusters like Tr37, astronomers can better constrain the timescales and physical processes governing stellar birth, disk evolution, and the long-term impact of stellar feedback on the interstellar medium.
