    Rayleigh-Taylor Instability in Partially Ionized Compressible Plasmas
    We study the modification of the classical criterion for the linear onset and growing rate of the Rayleigh-Taylor instability (RTI) in a partially ionized...

    Reconstructing the Photometric Light Curves of Earth as a Planet along Its History
    By utilizing satellite-based estimations of the distribution of clouds, we have studied Earth's large-scale cloudiness behavior according to latitude and...

    Reconstructing the Stellar Mass Distributions of Galaxies Using S4G IRAC 3.6 and 4.5 μm Images. II. The Conversion from Light to Mass
    We present a new approach for estimating the 3.6 μm stellar mass-to-light (M/L) ratio Upsilon3.6 in terms of the [3.6]-[4.5] colors of old stellar populations...

    Recovering Age-Metallicity Distributions from Integrated Spectra: Validation with MUSE Data of a Nearby Nuclear Star Cluster
    Current instruments and spectral analysis programs are now able to decompose the integrated spectrum of a stellar system into distributions of ages and...

    Recurrence of the Blue Wing Enhancements in the High-Ionization Lines of SDSS 1004+4112A
    We present integral field spectroscopic observations of the quadruple-lensed QSO SDSS 1004+4112 taken with the fiber system INTEGRAL at the William Herschel...

    Recurrent Strong Outbursts of an EXor-like Young Eruptive Star Gaia20eae
    We present follow-up photometric and spectroscopic observations, and subsequent analysis of Gaia20eae. This source triggered photometric alerts during 2020...

    Red giant stragglers and He white dwarfs in galactic globulars
    The evolutionary scenario concerning the production and the cooling of He white dwarfs is revisited and discussed. We show that, for a given star metallicity...

    Red Supergiants as Cosmic Abundance Probes: Massive Star Clusters in M83 and the Mass–Metallicity Relation of Nearby Galaxies
    We present an abundance analysis of seven super star clusters in the disk of M83. The near-infrared spectra of these clusters are dominated by red supergiants...
