Descripción
It is reported that 8-13-micron spectra have been obtained at several positions across the extended emission region of M82. No major differences among the spectra are found. In addition, a strong similarity is found between these spectra and the infrared spectrum of the Orion ionization front. The data are interpreted using a model for M82 in which the Orion nebula is taken as typical of a region of active star formation. A star burst model for M82 is constructed using 100,000 regions similar to Orion. The infrared spectral shape, overall luminosity, radio luminosity, and other observable parameters of M82 are consistent with this model. It is also suggested that models similar to the one proposed here may be used to explain the infrared spectrum of active galactic nuclei such as NGC 1614 and NGC 7469.

    The compact multi-planet system GJ 9827 revisited with ESPRESSO★

    GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then further characterized by other spectroscopic and photometric instruments. Previous literature studies provide several mass measurements for the three planets, however, with large variations

    Stellar halo density with LAMOST K and M giants

    Aims: We derive the morphology of the stellar component in the outer halo volume, and search for possible overdensities due to substructures therein. Methods: We made use of some of the data releases of the spectroscopic survey LAMOST DR8-DR9 in tandem with distance determinations for two subsamples, that is, of K-giants and M-giants, respectively

    Euclid preparation. XXXVII. Galaxy colour selections with Euclid and ground photometry for cluster weak-lensing analyses

    Aims: We derived galaxy colour selections from Euclid and ground-based photometry, aiming to accurately define background galaxy samples in cluster weak-lensing analyses. These selections have been implemented in the Euclid data analysis pipelines for galaxy clusters. Methods: Given any set of photometric bands, we developed a method for the
