Physics and phenomenology of galactic winds
Galactic winds are a crucial ingredient in galaxy evolution, but the physics of the ubiquitous outflowing high velocity gas seen from rapidly star-forming galaxies remains unknown. I will describe a s...

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...

The Milky Way Halo Stars toward the Galactic Center
The halo stars on highly radial orbits should inevitably pass the center regions of the Milky Way, although they are hard to be detected from the crowded bulge/bar. Under the assumption that the stell...

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...
