Gravitational Wave Memory and its stochastic background
<p>Gravitational wave memory is an outstanding theoretical prediction of general relativity. It may give an insight to fundamental physics such as quantum gravity. Alongwith the development of gravitational wave astronomy, the gravitational wave memory may be detected in the near future. In this talk I will introduce the physical picture of gravitational wave memory and its relation to fundamental...</p>

Physics and phenomenology of galactic winds
<p>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...</p>

A comprehensive survey of sub-stellar companions based on combined RV and astrometry method
<p>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...</p>

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...

The Configuration Formation of Exoplanetary Systems
To date, more than 3000 exoplanetary systems have been observed. Different kinds of planetary configurations are reported. Such as near-resonant configuration, closely packed multiple planetary system...

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 ...
