Formation and tidal evolution of hot super-Earths in multiple planetary systems [PDF]
, 2009 Hot super-Earths are exoplanets with masses < 10 Earth masses and orbital periods < 20 days. Around 8 hot super-Earths have been discovered in the neighborhood of solar system. In this lecture, we review the mechanisms for the formation of hot super-Earths, dynamical effects that play important roles in sculpting the architecture of the multiple ...

JWST/NIRSpec Prospects on Transneptunian Objects
Frontiers in Astronomy and Space Sciences, 2019 The transneptunian region has proven to be a valuable probe to test models of the formation and evolution of the solar system. To further advance our current knowledge of these early stages requires an increased knowledge of the physical properties of ...

EVOLUSI DINAMIK SUN'S BIRTH CLUSTER DAN PENCARIAN SOLAR SIBLINGS DI BIMASAKTI [PDF]
Wahana Fisika: Jurnal Penelitian Fisika dan Terapannya, 2019 Sebagian besar bintang-bintang di galaksi terbentuk di dalam gugus bintang, baik gugus terbuka maupun gugus bola. Begitu juga dengan Matahari, yang diperkirakan terbentuk pada 4,6 milyar tahun lalu di dalam sebuah gugus terbuka (sun’s birth cluster ...

The Astrophysical JournalThe Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 solar-like stars hosting ...

Atmospheres and surfaces of small bodies and dwarf planets in the Kuiper Belt
EPJ Web of Conferences, 2010 Kuiper Belt Objects (KBOs) are icy relics orbiting the sun beyond Neptune left over from the planetary accretion disk. These bodies act as unique tracers of the chemical, thermal, and dynamical history of our solar system.

Stellar neutron capture rates – key data for the s process
EPJ Web of Conferences, 2013 Neutron reactions are responsible for the formation of the elements heavier than iron. The corresponding scenarios relate to the He- and C- burning phases of stellar evolution (s process) and to supernova explosions (r and p processes).

Recurrent planetesimal formation in an outer part of the early solar system
Scientific ReportsThe formation of planets in our solar system encompassed various stages of accretion of planetesimals that formed in the protoplanetary disk within the first few million years at different distances to the sun.

New insight into the Solar System's transition disk phase provided by the unusual meteorite Isheyevo [PDF]
, 2014 Many aspects of planet formation are controlled by the amount of gas remaining in the natal protoplanetary disk (PPDs). Infrared observations show that PPDs undergo a transition stage at several Myr, during which gas densities are reduced. Our Solar System would have experienced such a stage.

Spitzer's Solar System Science Legacy: Studies of the Relics of Solar System Formation & Evolution. Part 1 - Comets, Centaurs, & Kuiper Belt Objects [PDF]
arXiv, 2020 In its 16 years of scientific measurements, the Spitzer Space Telescope performed a number of ground breaking and key infrared measurements of Solar System objects near and far. Targets ranged from the smallest planetesimals to the giant planets, and have helped us reform our understanding of these objects while also laying the groundwork for future ...
