    Refined parameters of the HD 22946 planetary system and the true orbital period of planet d★
    Context. Multi-planet systems are important sources of information regarding the evolution of planets. However, the long-period planets in these systems often...

    Refining the properties of the TOI-178 system with CHEOPS and TESS
    Context. The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from ~1.1...

    Relation between photospheric magnetic field and chromospheric emission
    Aims: We investigate the relationship between the photospheric magnetic field and the emission of the mid chromosphere of the Sun. Methods: We simultaneously...

    Relation of internal attenuation, dust emission, and the size of spiral galaxies. Calibration at low-z and how to use it as a cosmological test at high-z
    Aims: Dust in spiral galaxies produces emission in the far-infrared (FIR) and internal absorption in visible wavelengths. However, the relation of the two...

    Relations among structural parameters in barred galaxies with a direct measurement of bar pattern speed
    We investigate the relations between the properties of bars and their host galaxies in a sample of 77 nearby barred galaxies, spanning a wide range of...

    Relationships between cluster densities and other statistical quantities.
    We present a procedure for obtaining the cluster densities in terms of the probability, P_n_(r), for a randomly placed sphere of radius r to contain n galaxies...

    Relationships between magnetic foot points and G-band bright structures
    Aims:Magnetic elements are thought to be described by flux tube models, and are well reproduced by MHD simulations. However, these simulations are only...

    Removing systematics from the CoRoT light curves. I. Magnitude-dependent zero point
    This paper presents an analysis that searched for systematic effects within the CoRoT exoplanet field light curves. The analysis identified a systematic effect...

    Resolved Hubble space spectroscopy of ultracool binary systems
    Using the low-resolution mode of the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope (HST), we obtain spectra from 20 spatially...
