Estimation of Exoplanetary Planet-to-Star Radius Ratio with Homomorphic Processing
Rodrigo Mahu, Patricio Rojo, Ali Dehghan Firoozabadi +3
In this paper a homomorphic filtering scheme is proposed to improve the estimation of the planet/star radius ratio in astronomical transit signals. The idea is to reduce the effect…
Detection of titanium oxide in the atmosphere of a hot Jupiter
Elyar Sedaghati, Henri M. J. Boffin, Ryan J. MacDonald +6
As an exoplanet transits its host star, some of the light from the star is absorbed by the atoms and molecules in the planet's atmosphere, causing the planet to seem bigger; plotti…
Unsupervised Method for Correlated Noise Removal for Multi-wavelength Exoplanet Transit Observations
Ali Dehghan Firoozabadi, Alejandro Diaz, Patricio Rojo +4
Exoplanetary atmospheric observations require an exquisite precision in the measurement of the relative flux among wavelengths. In this paper, we aim to provide a new adaptive meth…
Probing the atmosphere of a sub-Jovian planet orbiting a cool dwarf
Elyar Sedaghati, Henri. M. J. Boffin, Laetitia Delrez +4
We derive the 0.01 m binned transmission spectrum, between 0.74 and 1.0 m, of WASP-80b from low resolution spectra obtained with the FORS2 instrument attached to ESO's Very L…
Regaining the FORS: optical ground-based transmission spectroscopy of the exoplanet WASP-19b with VLT+FORS2
E. Sedaghati, H. M. J. Boffin, Sz. Csizmadia +4
In the past few years, the study of exoplanets has evolved from being pure discovery, then being more exploratory in nature and finally becoming very quantitative. In particular, t…
Making FORS2 fit for exoplanet observations (again)
H. M. J. Boffin, G. Blanchard, O. A. Gonzalez +10
For about three years, it was known that precision spectrophotometry with FORS2 suffered from systematic errors that made quantitative observations of planetary transits impossible…
