Description
BVRI surface photometry is presented for the interacting galaxy pair Arp 86 (NGC 7753-7752). Deep high-resolution images were obtained in order to study the faint tidal features. The bridge was found to be bluer than the tail both in V - R and B - V, the V - R color probably suggesting enhanced long-term star formation in the bridge. The end of the bridge is extremely blue in B - V (0.2-0.4), thus indicating present ongoing star formation. The CCD images were also used to estimate initial parameters, such as inclinations and disk scale lengths for the dynamical modeling of Arp 86, presented in Salo and Laurikainen (1993).

    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
