Habitable Zone Lifetime of Exoplanets around Main Sequence Stars [PDF]

, 2013
Funding: Dean's Scholarship at the University of East Anglia.The potential habitability of newly discovered exoplanets is initially assessed by determining whether their orbits fall within the circumstellar habitable zone of their star.

Follow-Up and Validation of K2 and TESS Planetary Systems With Keck NIRC2 Adaptive Optics Imaging

Frontiers in Astronomy and Space Sciences, 2021
High resolution imaging (HRI) is a critical part of the transiting exoplanet follow-up and validation process. HRI allows previously unresolved stellar companions and background blends to be resolved, vetting false positive signals and improving the ...

Relationship between Luminosity, Irradiance and Temperature of star on the orbital parameters of exoplanets

EPJ Web of Conferences, 2013
For 759 exoplanets detected by radial velocities method we found that distances of exoplanets from central star comply in general Schmidt law and these distances depend on the stellar surface temperature.

Muons, mutations, and planetary shielding

Frontiers in Astronomy and Space Sciences, 2022
Life on earth is protected from astrophysical cosmic rays by the heliospheric magnetic and slowly varying geomagnetic fields, and by collisions with oxygen and nitrogen molecules in the atmosphere.

Three sub-Jupiter-mass planets: WASP-69b & WASP-84b transit active K dwarfs and WASP-70Ab transits the evolved primary of a G4+K3 binary [PDF]

, 2014
peer reviewedWe report the discovery of the transiting exoplanets WASP-69b, WASP-70Ab and WASP-84b, each of which orbits a bright star (V ˜ 10). WASP-69b is a bloated Saturn-mass planet (0.26 MJup, 1.06 RJup) in a 3.868-d period around an active, ˜1-Gyr,

Robo-AO and SOAR High-Resolution Surveys of Exoplanet Hosting Stars

Frontiers in Astronomy and Space Sciences, 2021
In the past decade, space-based transit surveys have delivered thousands of potential planet-hosting systems. Each of these needs to be vetted and characterized using follow-up high-resolution imaging.
