On-sky measurements of atmospheric dispersion: II. Atmospheric models characterization
B. Wehbe., A. Cabral, L. Sbordone +1
Differential atmospheric dispersion is a wavelength-dependent effect introduced by Earth's atmosphere that affects astronomical observations performed using ground-based telescopes…
MARVEL, a four-telescope array for high-precision radial-velocity monitoring
Gert Raskin, Christian Schwab, Bart Vandenbussche +23
Since the first discovery of a planet outside of our Solar System in 1995, exoplanet research has shifted from detecting to characterizing worlds around other stars. The TESS (NASA…
On-sky measurements of atmospheric dispersion: I. Method validation
B. Wehbe, A. Cabral, G. Avila
Observations with ground-based telescopes are affected by differential atmospheric dispersion due to the wavelength-dependent index of refraction of the atmosphere. The usage of an…
A crucial test for astronomical spectrograph calibration with frequency combs
Rafael A. Probst, Dinko Milaković, Borja Toledo-Padrón +23
Laser frequency combs (LFCs) are well on their way to becoming the next-generation calibration sources for precision astronomical spectroscopy. This development is considered key i…
The impact of atmospheric dispersion in the performance of high-resolution spectrographs
Bachar Wehbe, Alexandre Cabral, Jorge Martins +3
Differential atmospheric dispersion is a wavelength-dependent effect introduced by the atmosphere. It is one of the instrumental errors that can affect the position of the target a…
The development of an optical design tool for atmospheric dispersion correction
Bachar Wehbe, Alexandre Cabral, Gerardo Avila
In ground based astronomical observations, atmospheric dispersion shifts the image of the object at different wavelengths due to the wavelength-dependent index of refraction of the…
