چکیده

The advent of space-based photometry missions such as CoRoT, Kepler and TESS has sparkled the development asteroseismology exoplanetology. PLATO will further strengthen multi-disciplinary studies. Testing asteroseismic modelling its importance for our understanding planetary systems is crucial. We carried out a detailed Kepler-93, an exoplanet host star observed by Kepler. This particularly interesting it very similar to benchmark target (G spectral type, ~ 6000K, 1 Msun Rsun) provides real-life testbed potential procedures be used PLATO. use global local minimization techniques seismic varying ingredients stellar models. compute inversions mean density. these revised parameters provide new simulate orbital evolution system under effects tides atmospheric evaporation. Our fundamental Kepler-93: density = 1.654 +/- 0.004 g/cm3, M 0.907 0.023 , R 0.918 0.008 Rsun Age 6.78 0.32 Gyr. uncertainties we report this are within requirements For Kepler-93b, find Mp 4.01 0.67 Mearth, Rp 1.478 0.014 Rearth semi-major axis 0.0533 0.0005 AU. According simulations, seems unlikely that Kepler-93b formed with mass large enough impacted tides.

Planet Formation around Stars of Various Masses: Hot Super-earths

We consider trends resulting from two formation mechanisms for short-period super-Earths: planetplanet scattering and migration. We model scenarios where these planets originate near the snow line in “cold finger” circumstellar disks. Low-mass planet-planet scattering excites planets to low periastron orbits only for lower mass stars. With long circularisation times, these planets reside on lon...

Rapid Formation of Super-Earths around M Dwarf Stars

While the recent microlensing discoveries of super-Earths orbiting two M dwarf stars have been taken as support for the core accretion mechanism of giant planet formation, we show here that these planets could also have been formed by the competing mechanism of disk instability, coupled with photoevaporative loss of their gaseous envelopes by a strong external source of UV radiation, i.e., an O...

Variability of Kepler Solar-like Stars Harboring Small Exoplanets

We examine Kepler light-curve variability on habitable zone transit timescales for a large uniform sample of spectroscopically studied Kepler exoplanet host stars. The stars, taken from Everett et al., are solar-like in their properties and each harbors at least one exoplanet (or candidate) of radius „2.5 Re. The variability timescale examined is typical for habitable zone planets orbiting sola...

The Albedos of Kepler’ S Close-in Super-earths

Exoplanet research focusing on the characterization of super-Earths is currently limited to the handful of targets orbiting bright stars that are amenable to detailed study. This Letter proposes to look at alternative avenues to probe the surface and atmospheric properties of this category of planets, known to be ubiquitous in our galaxy. I conduct Markov Chain Monte Carlo light-curves analyses...

Evolution of Cold Circumstellar Dust around Solar-type Stars

We present submillimeter (Caltech Submillimeter Observatory 350 m) and millimeter (Swedish-ESO Submillimetre Telescope [SEST] 1.2 mm, Owens Valley Radio Observatory [OVRO] 3 mm) photometry for 127 solartype stars from the Formation and Evolution of Planetary Systems Spitzer Legacy program that have masses between 0.5 and 2.0 M and ages from 3 Myr to 3 Gyr. Continuum emission was detected toward...
