The TESS–Keck Survey. XXIV. Outer Giants May Be More Prevalent in the Presence of Inner Small Planets
We present the results of the Distant Giants Survey, a 3 yr radial velocity (RV) campaign to search for wide-separation giant planets orbiting Sun-like stars known to host an inner transiting planet. We defined a distant giant (DG) to have a =…

Precise Parameters from Bayesian Spectral Energy Distribution Fitting Indicate Thermally Driven Mass Loss Likely Driver of Radius Valley
Several planet formation models have been proposed to explain the gap in the population of planets between 1.8R⊕ to 2.0R⊕ known as the “radius valley.” To apply these models to confirmed exoplanets, accurate and precise host-star and…

Real-time Collision-free Motion Planning for Next-generation Fiber Positioners in LAMOST
Multiobject fiber-fed spectrographs have thousands of fiber positioners packed on a focal plane with shared working space to move the fiber-ends in parallel, which maximizes observation time. In order to further improve the spectrum acquiring…
