இலக்கியங்களில் கோள்களின் இயல்பு / Nature of Planets in Literature [PDF]
International Journal of Tamil Language and Literary Studies, 2022 The study of space objects and matter outside the earth’s atmosphere is called astronomy. Ancestors of Tamil culture undoubtedly had spectacular knowledge about astronomy. It is evident in Tamil literature.

Evolutionary models for cool brown dwarfs and extrasolar giant planets. The case of HD 209458 [PDF]
, 2003 We present evolutionary models for cool brown dwarfs and extra-solar giant planets. The models re- produce the main trends of observed methane dwarfs in near-IR color-magnitude diagrams.

Direct Imaging of Multiple Planets Orbiting the Star HR 8799 [PDF]
Science, 2008 Direct imaging of exoplanetary systems is a powerful technique that can reveal Jupiter-like planets in wide orbits, can enable detailed characterization of planetary atmospheres, and is a key step toward imaging Earth-like planets. Imaging detections are

THE OCCURRENCE OF POTENTIALLY HABITABLE PLANETS ORBITING M DWARFS ESTIMATED FROM THE FULL KEPLER DATASET AND AN EMPIRICAL MEASUREMENT OF THE DETECTION SENSITIVITY [PDF]
, 2015 We present an improved estimate of the occurrence rate of small planets orbiting small stars by searching the full four-year Kepler data set for transiting planets using our own planet detection pipeline and conducting transit injection and recovery ...

PLANET-PLANET SCATTERING IN PLANETESIMAL DISKS [PDF]
The Astrophysical Journal, 2009 We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt.

Ready functions for calculating the Martian radiation environment
Journal of Space Weather and Space Climate, 2019 It is extremely important to understand and model the Martian radiation environment in preparation for future human missions to Mars, especially during extreme and elevated conditions such as an intense solar energetic particle (SEP) event.

Debris disks as signposts of terrestrial planet formation. II Dependence of exoplanet architectures on giant planet and disk properties [PDF]
, 2011 We present models for the formation of terrestrial planets, and the collisional evolution of debris disks, in planetary systems that contain multiple unstable gas giants.

No large population of unbound or wide-orbit Jupiter-mass planets [PDF]
Nature, 2017 Planet formation theories predict that some planets may be ejected from their parent systems as result of dynamical interactions and other processes. Unbound planets can also be formed through gravitational collapse, in a way similar to that in which ...

Burying Earth's Primitive Mantle in the Slab Graveyard
Geochemistry, Geophysics, Geosystems, 2021 The evolution of mantle composition can be viewed as a process of destruction whereby the initial chemical state is overprinted and reworked with time.
