Orbital dynamics of two circumbinary planets around misaligned eccentric binaries [PDF]
, 2021 We investigate the orbital dynamics of circumbinary planetary systems with two planets around a circular or eccentric orbit binary. The orbits of the two planet are initially circular and coplanar to each other, but misaligned with respect to the binary orbital plane.

Accurate Empirical Radii and Masses of Planets and Their Host Stars with Gaia Parallaxes [PDF]
, 2016 We present empirical measurements of the radii of 116 stars that host transiting planets. These radii are determined using only direct observables—the bolometric flux at Earth, the effective temperature, and the parallax provided by the Gaia first data ...

Disc-planet, planet-planet, and star-planet interactions during planet formation
, 2003 In this article we present results from three on-going projects related to the formation of protoplanets in protostellar discs. We present the results of simulations that model the interaction between embedded protoplanets and disc models undergoing MHD turbulence.

Current Biology, 2005 What makes us humans so special? Our language, our genes, our culture, our cognitive skills? At the Max-Planck-Institute for Evolutionary Anthropology in Leipzig, psychologists, linguists and biologists tackle this old question in a truly multidisciplinary way. Their results have implications not just for our understanding of human evolution--they also

Музыкально-математико-астрономический синтез в трудах древнегреческих ученых
Вестник музыкальной науки, 2017 В статье рассматривается проблема единства музыкально-математико-астрономических представлений античных ученых начала первого тысячелетия - неопифагорейца Никомаха и выдающегося астронома Клавдия Птолемея на основе их малоизученных трудов.

The Densities of Planets in Multiple Stellar Systems [PDF]
, 2017 We analyze the effect of companion stars on the bulk density of 29 planets orbiting 15 stars in the Kepler field. These stars have at least one stellar companion within 2", and the planets have measured masses and radii, allowing an estimate of their ...

The California-Kepler Survey. V. Peas in a Pod: Planets in a Kepler Multi-planet System Are Similar in Size and Regularly Spaced [PDF]
, 2017 We have established precise planet radii, semimajor axes, incident stellar fluxes, and stellar masses for 909 planets in 355 multi-planet systems discovered by Kepler.

Radial Migration of Gap-opening Planets in Protoplanetary Disks. I. The Case of a Single Planet [PDF]
Astrophysical Journal, 2018 A large planet orbiting a star in a protoplanetary disk opens a density gap along its orbit due to the strong disk–planet interaction and migrates with the gap in the disk.

The Five Planets in the Kepler-296 Binary System All Orbit the Primary: A Statistical and Analytical Analysis [PDF]
, 2015 Kepler-296 is a binary star system with two M-dwarf components separated by 0.2 arcsec. Five transiting planets have been confirmed to be associated with the Kepler-296 system; given the evidence to date, however, the planets could in principle orbit ...

Observing the Atmospheres of Known Temperate Earth-sized Planets with JWST [PDF]
, 2017 Nine transiting Earth-sized planets have recently been discovered around nearby late-M dwarfs, including the TRAPPIST-1 planets and two planets discovered by the MEarth survey, GJ 1132b and LHS 1140b. These planets are the smallest known planets that may
