DOI: 10.1051/0004-6361/201629981
Abstract: Determining wavelength-dependent exoplanet radii measurements is an excellent way to probe the composition of exoplanet atmospheres. In light of this, sought to develop a technique to obtain such measurements by comparing ground-based transmission spectra to… read more here.

DOI: 10.1089/ast.2017.1737
Abstract: Abstract Finding life on exoplanets from telescopic observations is an ultimate goal of exoplanet science. Life produces gases and other substances, such as pigments, which can have distinct spectral or photometric signatures. Whether or not… read more here.

DOI: 10.1093/mnras/staa3962
Abstract: Recent exoplanet statistics indicate that photo-evaporation has a great impact on the mass and bulk composition of close-in low-mass planets. While there are many studies addressing photo-evaporation of hydrogen- or water-rich atmospheres, no detailed investigation… read more here.

DOI: 10.1093/mnras/stad1027
Abstract: Exomoons have so far eluded ongoing searches. Several studies have exploited transit and transit timing variations and high-resolution spectroscopy to identify potential exomoon candidates. One method of detecting and confirming these exomoons is to search… read more here.
