Super Earth refers to planets with a rocky core that has a radius of between 1.5 to 2 of that of Earth. They represent a class of exoplanets of significant scientific interest given the possibility of Earth-like habitability with respect to life, and is a target for observation by both space-based and Earth-based observatories. Thus … More What is a super-Earth in exoplanet research?
Feature article in Science, Vol. 356, Issue 6337, pp. 476-479, “A global robotic telescope network helps astronomers keep up with the fast-changing sky” Summary of article: Using standardized telescopes of diameter between 2 meter and 40 centimeters, a global network of automated telescopes lend clarity to distant stars, galaxies and even exoplanets through the … More Global network of standardized telescopes for time domain astronomy
Pluto is originally classified as the ninth planet of our Solar System, but it was reclassified as a dwarf planet in 2006 by the International Astronomical Union. On examination of the orbital characteristics of Pluto, my belief is that the planet is not a member of our Solar System, but rather, it orbits with a … More Pluto is not a planet of our Solar System
Detecting exoplanets in faraway solar systems is one of the hot topics in planetary science and exoplanets research, and is usually achieved with expensive space based and Earth-based telescopes. Specifically, a variety of methods such as transit and radial velocity detection have been successfully used in detecting small perturbations in the parent star luminosity and … More Not possible to do exploratory research on exoplanets with amateur Earth based telescopes
Exoplanets is one of the most exciting research fields in planetary science and astrophysics. Seeded in 1995 with the discovery of the first planets outside the Solar System, the field of exoplanets research have expanded rapidly with the use of more sensitive instruments capable of detecting the small drop in luminosity of the parent star, … More Low probability of expulsion of planets from a Solar System due to gravitational tug
