    CGCS 6306, another X-ray-emitting asymptotic giant branch star confirmed to be a symbiotic binary
    Context. A number of asymptotic giant branch (AGB) stars are known to exhibit UV excess and/or X-ray emission. These have been considered signposts of a hot...

    Challenging a Newtonian prediction through Gaia wide binaries
    Under Newtonian dynamics, the relative motion of the components of a binary star should follow a Keplerian scaling with separation. Once orientation effects and...

    Chandra and RXTE spectroscopy of the Galactic microquasar XTE J1550-564 in outburst
    On two occasions, we obtained nearly simultaneous ~=4 ks snapshot observations of the Galactic black hole and microquasar XTE J1550-564 with Chandra and RXTE...

    Chandra Observations of the X-Ray Jet of 3C 273
    We report results from Chandra observations of the X-ray jet of 3C 273 during the calibration phase in 2000 January. The zeroth-order images and spectra from...

    Changes in Earth's Reflectance over the Past Two Decades
    We correlate an overlapping period of earthshine measurements of Earth's reflectance (from 1999 through mid-2001) with satellite observations of global cloud...

    Changing Look of the Optical Spectrum of the MeV Blazar PKS 0446+112 (4FGL J0449.1+1121)
    Following the high activity of the γ-ray Fermi source 4FGL J0449.1+1121 (PKS 0446+112), possibly associated with a IceCube neutrino event IC-240105A, we...

    Channeling 5 Minute Photospheric Oscillations into the Solar Outer Atmosphere through Small-Scale Vertical Magnetic Flux Tubes
    We report two-dimensional MHD simulations which demonstrate that photospheric 5 minute oscillations can leak into the chromosphere inside small-scale vertical...

    Chaotic Behaviour of the Temporal Evolution of Star Formation Rate in the Solar Neighborhood
    We use statistical data giving the number of stars formed as a function of the age, assigned using the observed deterministic relation between chromospheric...
