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 ...

The tidal parameters of TRAPPIST-1b and c [PDF]

Monthly Notices of the Royal Astronomical Society, 2019
Abstract The TRAPPIST-1 planetary system consists of seven planets within 0.05 au of each other, five of which are in a multiresonant chain. These resonances suggest the system formed via planet migration; subsequent tidal evolution has damped away most of the initial eccentricities.

The nature of the TRAPPIST-1 exoplanets [PDF]

Astronomy & Astrophysics, 2018
Context. The TRAPPIST-1 system hosts seven Earth-sized, temperate exoplanets orbiting an ultra-cool dwarf star. As such, it represents a remarkable setting to study the formation and evolution of terrestrial planets that formed in the same protoplanetary disk.

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,

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.

On the Age of the TRAPPIST-1 System [PDF]

The Astrophysical Journal, 2017
Abstract The nearby (d = 12 pc) M8 dwarf star TRAPPIST-1 (2MASS J23062928−0502285) hosts a compact system of at least seven exoplanets with sizes similar to Earth. Given its importance for testing planet formation and evolution theories, and for assessing the prospects for habitability among Earth-size exoplanets orbiting the most common

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 ...

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 ...

Innovating Aircraft Repair Processes: The Role of Digitalization in Sustainability

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
This research explores how digitalization—by storing detailed non‐destructive testing data in structured DICONDE databases and creating a standard data model of the component—innovates aviation maintenance and repair processes. Coupled with a developed state‐based simulation model, it enables data‐driven, sustainable repair strategies that reduce waste,
