We report rest frequencies for rotational transitions of the deuterated ammonium isotopologues NH3D+, NH 2 D 2 + and NHD D 3 + , measured in a cryogenic ion trap machine. For the symmetric tops NH3D+ and NHD 3 + one and three transi...
ANALYTICAL INVESTIGATION OF THE DECREASE IN THE SIZE OF THE HABITABLE ZONE DUE TO A LIMITED CO2 OUTGASSING RATE [0.03%]
二氧化碳释放速率限制下的宜居带宽度缩减机制分析

The habitable zone concept is important because it focuses the scientific search for extraterrestrial life and aids the planning of future telescopes. Recent work has shown that planets near the outer edge of the habitable zone might not ac...
TEMPERATURE STRUCTURE AND ATMOSPHERIC CIRCULATION OF DRY TIDALLY LOCKED ROCKY EXOPLANETS [0.03%]

Next-generation space telescopes will observe the atmospheres of rocky planets orbiting nearby M-dwarfs. Understanding these observations will require well-developed theory in addition to numerical simulations. Here we present theoretical m...
Energy Deposition by Energetic Electrons in a Diffusive Collisional Transport Model [0.03%]

A considerable fraction of the energy in a solar flare is released as suprathermal electrons; such electrons play a major role in energy deposition in the ambient atmosphere, and hence the atmospheric response to flare heating. Historically...
In-situ Star Formation in the Outskirts of the Large Magellanic Cloud: Gaia DR2 Confirmation [0.03%]
大麦哲伦星云外围原位恒星形成：GAIA DR2确认结果

We explore the Gaia data release 2 (DR2) proper motions of six young, main-sequence stars, members of the Large Magellanic Cloud (LMC) reported by Moni Bidin et al. These stars are located in the outskirts of the disk, between 7° and 13° ...

The presence of SiS in space seems to be restricted to a few selected types of astronomical environments. It is long known to be present in circumstellar envelopes around evolved stars and it has also been detected in a handful of star-form...
Stability of CH3NCO in astronomical ices under energetic processing. A laboratory study [0.03%]
甲基异氰酸盐在天文学冰中的稳定性及其对能量处理的反应——基于实验室的研究

B Maté et al.
Methyl isocyanate (CH3NCO) was recently found in hot cores and suggested on comet 67P/CG. The incorporation of this molecule into astrochemical networks requires data on its formation and destruction. In this work, ices of pure CH3NCO and o...
Binarity and Accretion in AGB Stars: HST/STIS Observations of UV Flickering in Y Gem [0.03%]
红穗路易斯石的双星性与吸积：NGC 3293疏散星团HST / STIS观测到YGem紫外闪烁中的

Binarity is believed to dramatically affect the history and geometry of mass loss in AGB and post-AGB stars, but observational evidence of binarity is sorely lacking. As part of a project to search for hot binary companions to cool AGB star...

The liquid water habitable zone (HZ) describes the orbital distance at which a terrestrial planet can maintain above-freezing conditions through regulation by the carbonate-silicate cycle. Recent calculations have suggested that planets in ...

We present subarcsecond 1.3 mm continuum ALMA observations towards the Orion Molecular Cloud 1 South (OMC-1S) region, down to a spatial resolution of 74 AU, which reveal a total of 31 continuum sources. We also present subarcsecond 7 mm con...
