A comprehensive survey of sub-stellar companions based on combined RV and astrometry method
Very few sub-stellar companions have been found to orbit around main-sequence stars on wide orbits. The long period orbits of these objects are unlikely to be constrained by traditional methods such a...

How does stellar rotation impact their structure and evolution?
The traditional theory of stellar structure and evolution, presuming that stars formed and evolved in isolation, and the effect of rotation is negligible, is now a view of the past. Recent studies bas...

Does Jupiter form early?
Meteorites display an isotopic composition dichotomy between non-carbonaceous (NC) and carbonaceous (CC) groups, indicating that planetesimal formation in the solar protoplanetary disk occurred in two...

An early transition to magnetic supercriticality in star formation
Magnetic fields play an important role in the evolution of interstellar medium and star formation. As the only direct tracer of interstellar field strength, credible Zeeman measurements remain sparse ...
