T Chamaeleontis:
Astronomers used archival spectroscopic data from NASA’s James Webb Space Telescope Mid Infrared Instrument (MIRI) to study polycyclic aromatic hydrocarbons (PAHs) in the spectrum of the young star T.Chamaeleontis.
- T Chamaeleontis is a young but sun-like star in the small southern constellation of Chamaeleon.
- It is located about 350 light-years from Earth.
- It can be found in southern celestial hemisphere.
- It is approximately 70 % of the size of Sun and temperature on its surface is around 4838 °C.
- It is surrounded by a planet-forming disk called circumstellar disk that contains a wide gap, likely carved out by an emerging protoplanet.
- Normally, the dense inner regions of such disks act like a protective wall or veil blocking much of the star’s ultraviolet light from reaching the colder, outer regions.
- This gap makes the system a key target for studying how young planets interact with their natal disks and shape their surrounding environments during the early stages of planet formation.
