Descripción
Near-infrared maps in the J, H, and K bands, have been obtained for the nearby flocculent spiral NGC 2403, with a linear resolution of 900 pc. Radially and azimuthally averaged profiles, and profiles in colour index are presented. The maps and the annular profiles show the presence of near-infrared spiral arms, whose contrast with the disc is determined. We are able to analyze the maps in terms of the disc component in the near IR. We have also obtained U, B, V maps with comparable resolution from which visible-infrared colour indices have been derived.

    High-resolution Spectroscopic Reconnaissance of a Temperate Sub-Neptune
    The study of temperate sub-Neptunes is the new frontier in exoplanetary science. A major development in the past year has been the first detection of carbon-bearing molecules in the atmosphere of a temperate sub-Neptune, K2-18 b, a possible Hycean world, with the James Webb Space Telescope (JWST). The JWST is poised to characterize the atmospheres

    Identification of the Top TESS Objects of Interest for Atmospheric Characterization of Transiting Exoplanets with JWST
    JWST has ushered in an era of unprecedented ability to characterize exoplanetary atmospheres. While there are over 5000 confirmed planets, more than 4000 Transiting Exoplanet Survey Satellite (TESS) planet candidates are still unconfirmed and many of the best planets for atmospheric characterization may remain to be identified. We present a sample

    Nonlinear Wave Damping by Kelvin–Helmholtz Instability-induced Turbulence
    Magnetohydrodynamic kink waves naturally form as a consequence of perturbations to a structured medium, for example, transverse oscillations of coronal loops. Linear theory has provided many insights into the evolution of linear oscillations, and results from these models are often applied to infer information about the solar corona from observed
