We report the discovery of HN Lib b, a sub-Neptunian mass planet orbiting the nearby (d≈ = 6.25 pc) M4.0 V star HN Lib detected by our CARMENES radial-velocity (RV) survey.

Core components of EELS robot, including perception head, shape actuators that connect each body segment, screws attached to each module, and the tether for data and electrical power transfer. -- NASA

Figure (a) and (c) show the initial light curve and the river plot for TOI-4622, respectively. The light curve is folded over seven transits and the river plot shows the evolution of the noisy periodic transit signals over the course of the entire light curve. Figure (b) and (d) show the denoised versions of these plots after the implementation of SSA. The SNR of the transit has increased from 13.37 to 15.59. -- astro-ph.EP

An example of the detrending process as applied to data taken on July 16 2011. Top panel: the data after extraction using the CRIRES pipeline and the correction of bad pixels. Middle panel: the same data after aligning and normalising the spectra. Bottom panel: the final de-trended data after applying SYSREM, a high pass filter, and dividing each column by its standard deviation. Particularly noisy regions of the data have also been masked. It is the de-trended data presented in the bottom panel that is used in the subsequent Doppler tomography and cross-correlation analysis. -- astro-ph.EP
