1-24 (24 pages) This tutorial is an introduction to techniques used to characterize the atmospheres of transiting exoplanets. We intend it to ... phase curves, transit spectroscopy, and convolution ...

As planets pass in front of their parent stars as viewed from Earth, they cause a tiny dip in the amount of starlight we ...

Astronomers measured how light from each parent star is filtered through each planet's atmosphere. HAT-P-38 b did have a water signature indicated by the absorption-feature peak in the spectrum.

An alien world with a seemingly sulphur-filled atmosphere may be the most volcanic ... aren’t powerful enough to take images of exoplanets’ surfaces. We might be able to spot alien volcanoes ...

Astronomers largely circumvent this problem by instead observing the side of an exoplanet ... and atmosphere. However, such observations are more time-consuming than transit spectroscopy.

STEP 1: After learning about the different methods used to find exoplanets ... identify the atmospheric composition of each planet they’ve discovered by analyzing the unique absorption spectrum ...

WASP-17 b is one of the largest and puffiest known exoplanets. This, along with its short orbital period of just 3.7 Earth-days, makes the planet ideal for transmission spectroscopy: a technique ...

One of the big highlights of the release of the first science data from the James Webb Space Telescope was the spectrum of an exoplanet atmosphere ... Object Slitless Spectroscopy (SOSS) mode.

The transmission spectrum of the exoplanet WASP-39b is obtained using observations from the Single-Object Slitless Spectroscopy ... absorption feature at 4.05 μm arising from SO 2 in the ...

Using NASA's exoplanet-hunter TESS (Transiting ... shines through a transiting planet's atmosphere or even debris around it, the characteristic absorption of light by the elements can also leave ...
