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.

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 ...

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.

Nonlinear dynamics of the Trappist-1-Trappist-1e exoplanetary system
, 2023 Abstract I addition to the various methods on the study of exoplanetary systems, the case of the circular restricted three body problem can be used, among others, to determine the character of the orbits of an astronomical body which moves under the action of the gravitational field of two massive bodies such as star-planets or binary star ...

Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1 [PDF]
Nature, 2017 One aim of modern astronomy is to detect temperate, Earth-like exoplanets that are well suited for atmospheric characterization. Recently, three Earth-sized planets were detected that transit (that is, pass in front of) a star with a mass just eight per ...

Palamism Does Not Disfigure the Gospel: A Reply to Thomas Weinandy
International Journal of Systematic Theology, EarlyView.Abstract In a 2024 article in the IJST, Fr. Thomas Weinandy argues that the theological system of Gregory Palamas is in grave error, especially with respect to its commitment to an objective ontological distinction between God's essence and His energies. In his concluding paragraph Fr.

Doctrine, Narrative and the Formation of Christian Identity: A Conversation with Alister McGrath
International Journal of Systematic Theology, EarlyView.Abstract This article offers a critical and appreciative response to Alister McGrath’s The Nature of Christian Doctrine, exploring the formation of doctrine as a dynamic communal process rooted in Scripture, liturgy and historical context. It highlights McGrath’s analogy between doctrinal development and scientific method, emphasising the search for a ...
