Possible Transfer of Life by Earth-Grazing Objects to Exoplanetary Systems
Life, 2020 Recently, a 30-cm object was discovered to graze the Earth’s atmosphere and shift into a Jupiter-crossing orbit. We use the related survey parameters to calibrate the total number of such objects.

The California-Kepler Survey. IV. Metal-rich Stars Host a Greater Diversity of Planets [PDF]
, 2017 Probing the connection between a star’s metallicity and the presence and properties of any associated planets offers an observational link between conditions during the epoch of planet formation and mature planetary systems. We explore this connection by

Progress in Earth and Planetary Science, 2023 The thermal structure of subduction zones is fundamental to our understanding of the physical and chemical processes that occur at active convergent plate margins. These include magma generation and related arc volcanism, shallow and deep seismicity, and

Planet-Planet Tides in the TRAPPIST-1 System [PDF]
Res. Notes AAS, 2, 175, 2018 The star TRAPPIST-1 hosts a system of seven transiting, terrestrial exoplanets apparently in a resonant chain, at least some of which are in or near the Habitable Zone. Many have examined the roles of tides in this system, as tidal dissipation of the orbital energy of the planets may be relevant to both the rotational and orbital dynamics of the ...

, 2002 Most extrasolar planets are observed to have eccentricities much larger than those in the solar system. Some of these planets have sibling planets, with comparable masses, orbiting around the same host stars.

The GAPS Programme with HARPS-N at TNG - XIV. Investigating giant planet migration history via improved eccentricity and mass determination for 231 transiting planets [PDF]
, 2017 We carried out a Bayesian homogeneous determination of the orbital parameters of 231 transiting giant planets (TGPs) that are alone or have distant companions; we employed differential evolution Markov chain Monte Carlo methods to analyse radial-velocity

Lo stato dell’arte nella ricerca dei pianeti extrasolari di tipo terrestre [PDF]
S&F_scienzaefilosofia.it, 2023 State of the art in the search for extrasolar planets In the last three decades, the study of exoplanets has evolved from a marginal field into a vital area of research with significant implications for other sciences and philosophy. In this article, we

AGU Advances, 2021 The nature and cause of deep earthquakes remain enduring unknowns in the field of seismology. We present new models of thermal structures of subducted slabs traced to mantle transition zone depths that permit a detailed comparison between slab pressure ...

Tilted circumbinary planetary systems as efficient progenitors of free-floating planets [PDF]
arXiv, 2023 The dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet-planet interactions. However, instability around a single star requires a very compactly spaced planetary system.
