Astrometric Constraints on the Masses of Long-Period Gas Giant Planets in the TRAPPIST-1 Planetary System

"...no planet more massive than ∼4.6MJup orbits with a 1 yr period, and no planet more massive than ∼1.6MJup orbits with a 5 yr period."

Color difference makes a difference: four planet candidates around tau Ceti

" We apply this noise model to various radial velocity data sets for tau Ceti, and find four periodic signals at 20.0, 49.3, 160 and 642 d which we interpret as planets."

Tidal Locking of Habitable Exoplanets

"Lower mass stellar hosts will induce stronger tidal effects on potentially habitable planets, and tidal locking is possible for most planets in the habitable zones of GKM dwarf stars."

Temporal evolution of the high-energy irradiation and water content of TRAPPIST-1 exoplanets

"Based on the current knowledge of the stellar irradiation, we investigated the likely history of water loss in the system. Planets b to d might still be in a runaway phase, and planets within the orbit of TRAPPIST-1g could have lost more than 20 Earth oceans after 8 Gyr of hydrodynamic escape. However, TRAPPIST-1e to h might have lost less than 3 Earth oceans if hydrodynamic escape stopped once they entered the habitable zone."

Habitable Climate Scenarios for Proxima Centauri b With a Dynamic Ocean

"We find that an ocean-covered Proxima b could have a much broader area of surface liquid water but at much colder temperatures than previously suggested, due to ocean heat transport and depression of the freezing point by salinity."

Lecture notes on the formation and early evolution of planetary systems

"These notes provide an introduction to the theory of the formation and early evolution of planetary systems. Topics covered include the structure, evolution and dispersal of protoplanetary disks; the formation of planetesimals, terrestrial and gas giant planets; and orbital evolution due to gas disk migration, planetesimal scattering, planet-planet interactions, and tides."

Challenges in Planet Formation

"Here we review our state of understanding of five fundamental bottlenecks in planet formation. These are: 1) the structure and evolution of protoplanetary disks; 2) the growth of the first planetesimals; 3) orbital migration driven by interactions between proto-planets and gaseous disk; 4) the origin of the Solar System's orbital architecture; and 5) the relationship between observed super-Earths and our own terrestrial planets."

How alien can alien worlds be?

"Our results show that if rocky planets orbit these stars they might have significantly different compositions between themselves and different from that of our Earth."

Is Life Most Likely Around Sun-like Stars?

"We conclude that planets orbiting most M-dwarfs are not likely to host life, and that the highest probability of complex biospheres is for planets around K- and G-type stars."
