FAST Search for Circumstellar Atomic Hydrogen. III. Planetary Nebulae at Galactic Latitudes ∣b∣ ≥ 10°
The detection of circumstellar atomic hydrogen (H i) via the 21 cm line remains a persistent challenge in planetary nebula (PN) studies, primarily due to contamination from ubiquitous interstellar H i 21 cm emission. In this paper, we report the…

A Comprehensive Analysis of Rovibrational CO in the Era of JWST
We present an analysis of CO rovibrational emission lines in the 183 infrared spectra of nearby Class II objects obtained with the NIRSPEC instrument on the Keck II telescope over the past two decades. The sample includes a broad range of stellar…

A 16 Myr Super-Neptune in Upper Centaurus Lupus and a Preliminary Survey of Transiting Planets in Sco-Cen with TESS
Measuring the properties of planets younger than about 50 Myr helps to test different planetary formation and evolution models. NASA’s Transiting Exoplanet Survey Satellite (TESS) has observed nearly the entire sky, including a wide range of…

New Research Sheds Light on Evolution of Lava Planets
Lava planets are rocky exoplanets that orbit so close to their host star that their dayside is hot enough to melt silicate rock.
Boukaré et al. introduce a simple theoretical framework to describe the evolution of the coupled…
