Non-Thermal Nitric Oxide Formation in the Earth’s Polar Atmosphere

open access: yesAtmosphere, 2023
Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres because they are closely related to the stellar energy deposition by and evolution of planetary atmospheres.

GJ 357 d: Potentially Habitable World or Agent of Chaos?

open access: yesThe Astronomical Journal, 2023
Multiplanet systems provide important laboratories for exploring dynamical interactions within the range of known exoplanetary system architectures. One such system is GJ 357, consisting of a low-mass host star and three orbiting planets, the outermost ...

The Kinetic Monte Carlo Model of the Auroral Electron Precipitation into N2-O2 Planetary Atmospheres

open access: yesUniverse, 2022
Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres. They are closely related to the energy deposition by and evolution of planetary atmospheres, and their observations are widely used to analyze the ...

Evolution of a Water-rich Atmosphere Formed by a Giant Impact on an Earth-sized Planet

open access: yesThe Astrophysical Journal, 2023
The atmosphere of a terrestrial planet that is replenished with secondary gases should have accumulated hydrogen-rich gas from its protoplanetary disk.

Near Mean Motion Resonance of Terrestrial Planet Pair Induced by Giant Planet: Application to Kepler-68 System [PDF]

open access: yesMNRAS, 496, 4688-4699 (2020), 2020
In this work, we investigate configuration formation of two inner terrestrial planets near mean motion resonance (MMRs) induced by the perturbation of a distant gas-giant for the Kepler-68 system, by conducting thousands of numerical simulations. The results show that the formation of terrestrial planets is relevant to the speed of Type I migration ...

The Occurrence Rate of Terrestrial Planets Orbiting Nearby Mid-to-late M Dwarfs from TESS Sectors 1–42

open access: yesThe Astronomical Journal, 2023
We present an analysis of a volume-complete sample of 363 mid-to-late M dwarfs within 15 pc of the Sun with masses between 0.1 and 0.3 M _⊙ observed by TESS within sectors 1–42. The median stellar mass of the sample is 0.17 M _⊙ .

Puzzling out the coexistence of terrestrial planets and giant exoplanets. The 2/1 resonant periodic orbits [PDF]

open access: yes, 2018
Hundreds of giant planets have been discovered so far and the quest of exo-Earths in giant planet systems has become intriguing. In this work, we aim to address the question of the possible long-term coexistence of a terrestrial companion on an orbit ...
