Study unveils the dual nature of a young stellar object
Phys.org••technology
Key Points:
- Astronomers from ARIES and collaborators conducted a long-term photometric and spectroscopic study of the young stellar object V1180 Cassiopeiae, revealing its dual nature as both an EXor and UXor type variable star.
- V1180 Cassiopeiae, located about 1,950 light-years away, was initially classified as an EXor but later showed variability typical of UXor stars, prompting a detailed investigation combining data from 1999 to 2025.
- The study found complex brightness variations with both extinction-driven dimming events and accretion-related changes, supported by color-magnitude diagrams and emission line diagnostics indicating evolving disk structure and linked outflow-extinction processes.
- Results demonstrate that V
