Hot Jupiters were the first exoplanets to be discovered around main sequence stars and
astonished us with their close-in orbits. They are a prime example of how exoplanets have …

The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), also known as
the Guoshoujing Telescope, is a major national scientific facility for astronomical research …

Probing the connection between a star's metallicity and the presence and properties of any
associated planets offers an observational link between conditions during the epoch of …

One bottleneck for the exploitation of data from the Kepler mission for stellar astrophysics
and exoplanet research has been the lack of precise radii and evolutionary states for most of …

Studies of exoplanet demographics require large samples and precise constraints on
exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the …

Recent studies have shown that atmospheric mass-loss powered by the cooling luminosity
of a planet's core can explain the observed radius valley separating super-Earths and sub …

We constrain the intrinsic architecture of Kepler planetary systems by modeling the observed
multiplicities of the transiting planets (tranets) and their transit timing variations (TTVs). We …

In the past few years, significant advances have been made in understanding the
distributions of exoplanet populations and the architecture of planetary systems. We review …

A planetary atmosphere is the outer gas layer of a planet. Besides its scientific significance
among the first and most accessible planetary layers observed from space, it is closely …

Using radial velocity data from the Habitable Zone Planet Finder, we have measured the
mass of the Neptune-sized planet K2-25b, as well as the obliquity of its M4. 5 dwarf host star …
