Planets Across Space and Time (PAST). III. Morphology of the Planetary Radius Valley as a Function of Stellar Age and Metallicity in the Galactic Context Revealed by the LAMOST-Gaia-Kepler Sample
Di-Chang Chen, Ji Wei Xie, Ji-Lin. Zhou +7
The radius valley, a dip in the radius distribution of exoplanets at ~1.9 Earth radii separates compact rocky Super-Earths and Sub-Neptunes with lower density. Various hypotheses h…
Vertical structure of Galactic disk kinematics from LAMOST K giants
Ping-Jie Ding, Xiang-Xiang Xue, Chengqun Yang +3
We examine the vertical structure of Galactic disk kinematics over a Galactocentric radial distance range of and up to away from the Galactic pla…
Comparison of multifrequency positions of extragalactic sources from global geodetic VLBI monitoring program and Gaia EDR3
Niu Liu, Sebastien Lambert, Patrick Charlot +5
We extend previous works by considering two additional radio frequencies (K band and X/Ka band) with the aim to study the frequency dependence of the source positions and its poten…
Systematics and accuracy of VLBI astrometry: What can be learned from a comparison with Gaia Data Release 2
Niu Liu, Sebastien Lambert, Zi Zhu +1
We aim to investigate the overall properties of the ICRF3 with the help of the Gaia Data release 2 (Gaia DR2). This could serve as an external check of the quality of the ICRF3. Th…
Analyses of celestial pole offsets with VLBI, LLR, and optical observations
Yu-Ting Cheng, Jia-Cheng Liu, Zi Zhu
This work aims to explore the possibilities of determining the long-period part of the precession-nutation of the Earth with techniques other than very long baseline interferometry…
