Article Synopsis
- Researchers are studying the multi-scale interstellar medium (ISM) of our Galaxy to understand the relationships between gas, dust, and star formation in Giant Molecular Clouds (GMCs).
- The Milky Way's complex structure is influenced by massive stars and dust lanes, making it essential to observe these features at (sub-)millimeter wavelengths for in-depth analysis.
- A proposed 50m single-dish sub-mm telescope called AtLAST aims to provide comprehensive observations of the Galactic Plane and surrounding areas to enhance our understanding of stellar formation, planetary system evolution, and the overall ecology of our Galaxy.
Although planets are being discovered around stars more massive than the Sun, information about the proto-planetary disks where such planets have built up is sparse. We have imaged mid-infrared emission from polycyclic aromatic hydrocarbons at the surface of the disk surrounding the young intermediate-mass star HD 97048 and characterized the disk. The disk is in an early stage of evolution, as indicated by its large content of dust and its hydrostatic flared geometry, indicative of the presence of a large amount of gas that is well mixed with dust and gravitationally stable.
