... When we look at other star systems, one of the first things we look for is what’s called the “habitable zone”. This is the area in the star system where you’d be just the right distance for water to be liquid. Why? Because it might mean a planet like Earth that we could someday colonize. So what fac ...

What is a planet? - X-ray and Observational Astronomy Group
... • We record this brightening, which can last for days • If the lensed star has a planetary companion, the characteristic lensing light curve is modified • Signals from an Earth-like planet would be strong (>5%) but brief (few hours) • 4 planets found so far, including one at 5.5 Earth masses! ...

Effects of Mutual Transits by Extrasolar Planet
... monitoring 105 stars for three years with Kepler may lead to a discovery of a second EarthMoon-like system if the fraction is larger than 0.05, or it may put upper limits on the fraction as f < (pNS )−1 ∼ 0.05(3yr/Tobs )(105 /NS ). We should note that there exist constraints due to some physical mec ...

Activity I: Plotting a Light Curve due to a Transit

The first time the transit method was used was to confirm a planet orbiting around a star known as HD209458. The pl ...
