Pre-perihelion radio observations of comet 12P/Pons-Brooks with Tianma radio telescope
Juncen Li, Xian Shi, Jianchun Shi +7
{The multiple outburst events of comet 12P/Pons-Brooks during its 2024 apparition offer a unique window into highly-active volatile releasing processes not observable during quiesc…
FAST Observations of Four Comets to Search for the Molecular Line Emissions between 1.0 and 1.5 GHz Frequencies
Long-Fei Chen, Chao-Wei Tsai, Jian-Yang Li +11
We used the Five-hundred-meter Aperture Spherical radio Telescope (FAST) to search for the molecular emissions in the L-band between 1.0 and 1.5 GHz toward four comets, C/2020 F3 (…
New constraints on Triton's atmosphere from the 6 October 2022 stellar occultation
Ye Yuan, Chen Zhang, Fan Li +46
The atmosphere of Triton was probed directly by observing a ground-based stellar occultation on 6 October 2022. This rare event yielded 23 positive light curves collected from 13 s…
Millimeter-sized Dust Grains Appear Surviving the Water-sublimating Temperature in the Inner 10 au of the FU Ori Disk
Hauyu Baobab Liu, An-Li Tsai, Wen Ping Chen +10
Previous observations have shown that the 10 au, 400 K hot inner disk of the archetypal accretion outburst young stellar object, FU Ori, is dominated by viscous…
Asteroid (3200) Phaethon: colors, phase curve, limits on cometary activity and fragmentation
Maryam Tabeshian, Paul Wiegert, Quanzhi Ye +3
We report on a multi-observatory campaign to examine asteroid 3200 Phaethon during its December 2017 close approach to Earth, in order to improve our measurements of its fundamenta…
Qatar Exoplanet Survey: Qatar-8b, 9b and 10b --- A Hot Saturn and Two Hot Jupiters
Khalid Alsubai, Zlatan I. Tsvetanov, Stylianos Pyrzas +27
In this paper we present three new extrasolar planets from the Qatar Exoplanet Survey (QES). Qatar-8b is a hot Saturn, with Mpl = 0.37 Mjup and Rpl = 1.3 Rjup, orbiting a solar-lik…
