The Demographics of Exoplanets [PDF]

open access: yes, 2021
In the broadest sense, the primary goal of exoplanet demographic surveys is to determine the frequency and distribution of planets as a function of as many of the physical parameters that may influence planet formation and evolution as possible, over as broad of a range of these parameters as possible.

Investigating Exoplanet Orbital Evolution Around Binary Star Systems with Mass Loss [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2016
A planet revolving around binary star system is a familiar system. Studies of these systems are important because they provide precise knowledge of planet formation and orbit evolution. In this study, a method to determine the evolution of an exoplanet

Application of transit timing variation method (TTV) to exoplanet system TrES-3

open access: yesВісник Астрономічної школи, 2015
On the basis of the original photometric data, the light curves of several transits in the exoplanet system TrES-3 were simulated by Monte Carlo method. Using these curves, the estimates of precise values of mid-transit time were calculated to assess the

The Peak Absorbance Wavelength of Photosynthetic Pigments Around Other Stars From Spectral Optimization

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In the search for life on other planets, the presence of photosynthetic surface vegetation may be detectable from the colors of light it reflects. On the modern Earth, this spectral reflectance is characterized by a steep increase in reflectance between ...
