Interior Characterization in Multiplanetary Systems: TRAPPIST-1 [PDF]
The Astrophysical Journal, 2018 Abstract Interior characterization traditionally relies on individual planetary properties, ignoring correlations between different planets of the same system. For multiplanetary systems, planetary data are generally correlated. This is because the differential masses and radii are better constrained than absolute planetary masses and ...

TRAPPIST Habitable Atmosphere Intercomparison (THAI) Workshop Report [PDF]
The Planetary Science Journal, 2021 Abstract The era of atmospheric characterization of terrestrial exoplanets is just around the corner. Modeling prior to observations is crucial in order to predict the observational challenges and to prepare for the data interpretation.

Stellar Parameters for Trappist-1 [PDF]
The Astrophysical Journal, 2018 Abstract TRAPPIST-1 is an ultracool dwarf star transited by seven Earth-sized planets, for which thorough characterization of atmospheric properties, surface conditions encompassing habitability, and internal compositions is possible with current and next-generation telescopes.

Tides Between the TRAPPIST-1 Planets [PDF]
The Astrophysical Journal, 2019 Abstract The TRAPPIST-1 system is sufficiently closely packed that tides raised by one planet on another are significant. We investigate whether this source of tidal heating is comparable to eccentricity tides raised by the star. Assuming a homogeneous body with a Maxwell rheology, we find that energy dissipation from stellar tides ...

Sitientibus Série Ciências Físicas, 2020 A abordagem central baseia-se no problema de três corpos, em que é analisada a dinâmica secular de um sistema composto por uma estrela central e dois planetas sob influência gravitacional mútua, considerando a perturbação devido ao efeito da atração gravitacional do terceiro corpo em órbita elíptica e inclinada até a terceira ordem do potencial ...

PROBING TRAPPIST-1-LIKE SYSTEMS WITH K2 [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT The search for small planets orbiting late M dwarfs holds the promise of detecting Earth-size planets for which their atmospheres could be characterized within the next decade. The recent discovery of TRAPPIST-1 entertains hope that these systems are common around hosts located at the bottom of the main sequence. In this Letter,

The Carbon-deficient Evolution of TRAPPIST-1c
The Astrophysical Journal, 2023 Abstract Transiting planets orbiting M dwarfs provide the best opportunity to study the atmospheres of rocky planets with current facilities. As JWST enters its second year of science operations, an important initial endeavor is to determine whether these rocky planets have atmospheres at all.

Magma Ocean Evolution of the TRAPPIST-1 Planets
Astrobiology, 2021 Recent observations of the potentially habitable planets TRAPPIST-1 e, f, and g suggest that they possess large water mass fractions of possibly several tens of weight percent of water, even though the host star's activity should drive rapid atmospheric escape.
