Simulation Of The Earth’s Radio Leakage From Mobile Towers As Seen From Selected Nearby Stellar Systems
Mobile communication towers represent a relatively new but growing contributor to the total radio leakage associated with planet Earth.
Narrow Loophole for H2-dominated Atmospheres On Habitable Rocky Planets Around M Dwarfs
Habitable rocky planets around M dwarfs that have H2-dominated atmospheres, if they exist, would permit characterizing habitable exoplanets with detailed spectroscopy using JWST, owing to their extended atmospheres and small […]
Warm Giant Exoplanet Characterisation: Current State, Challenges And Outlook
The characterisation of giant exoplanets is crucial to constrain giant planet formation and evolution theory and for putting the solar-system’s giant planets in perspective.
Prospects For The Characterization Of Habitable Planets
With thousands of exoplanets now identified, the characterization of habitable planets and the potential identification of inhabited ones is a major challenge for the coming decades.
There’s More To Life Than O2: Simulating the Detectability Of A Range Of Molecules For Ground-based high-resolution Spectroscopy Of Transiting Terrestrial Exoplanets
Within the next decade, atmospheric O2 on Earth-like M dwarf planets may be accessible with visible–near-infrared, high spectral resolution extremely large ground-based telescope (ELT) instruments.
Lorenz Energy Cycle: Another Way to Understand the Atmospheric Circulation on Tidally Locked Terrestrial Planets
In this study, we employ and modify the Lorenz energy cycle (LEC) framework as another way to understand the atmospheric circulation on tidally locked terrestrial planets.
Detection of Carbon Monoxide’s 4.6 Micron Fundamental Band Structure In WASP-39b’s Atmosphere With JWST NIRSpec G395H
Carbon monoxide (CO) is predicted to be the dominant carbon-bearing molecule in giant planet atmospheres, and, along with water, is important for discerning the oxygen and therefore carbon-to-oxygen ratio of […]
Two Warm Super-Earths Transiting the Nearby M Dwarf TOI-2095
We report the detection and validation of two planets orbiting TOI-2095 (TIC 235678745). The host star is a 3700K M1V dwarf with a high proper motion. The star lies at […]
Constellations of co-orbital planets: horseshoe dynamics, long-term stability, transit timing variations, and potential as SETI beacons
Co-orbital systems contain two or more bodies sharing the same orbit around a planet or star. The best-known flavors of co-orbital systems are tadpoles (in which two bodies’ angular separations […]
