Interferometric apodization by homothety -- II. Experimental validation
J Chafi, Y El Azhari, O Azagrouze +4
This work presents the results of experimental laboratory tests on the apodization of circular and rectangular apertures using the Interferometric Apodization by Homothety (IAH) te…
Interferometric apodization by homothety -- I. Optimization of the device parameters
Jamal Chafi, Youssef El Azhari, Ossama Azagrouze +4
This study is focused on the very high dynamic imaging field, specifically the direct observation of exoplanetary systems. The coronagraph is an essential technique for suppressing…
An extended low-density atmosphere around the Jupiter-sized planet WASP-193 b
Khalid Barkaoui, Francisco J. Pozuelos, Coel Hellier +32
Gas giants transiting bright nearby stars provide crucial insights into planetary system formation and evolution mechanisms. Most of these planets exhibit certain average character…
Surface pressure impact on nitrogen-dominated USP super-Earth atmospheres
Jamila Chouqar, Jacob Lustig-Yaeger, Zouhair Benkhaldoun +3
In this paper, we compare the chemistry and the emission spectra of nitrogen-dominated cool, warm, and hot ultra-short-period (USP) super-Earth atmospheres in and out of chemical e…
Activity and composition of the hyperactive comet 46P/Wirtanen during its close approach in 2018
Y. Moulane, E. Jehin, J. Manfroid +10
Hyperactive comets are a small group of comets whose activity are higher than expected. They seem to emit more water than they should based on the size of their nucleus and comet 4…
