This month, we look at the contribution of 'pseudo shocks' to coronal heating, the equation of state of very massive stars and the primordial abundance of helium in intergalactic gas clouds...

    Accretion onto the surface of a white dwarf typically generates supersoft X-ray emission and broad emission lines due to nuclear fusion. ASASSN-16oh exhibits no visible broad lines, implying there is no surface fusion, and instead, a belt around the dwarf called a spreading layer is the source of the supersoft X-ray emission.

    Moving shadows have been seen on the circumbinary disk around V4046 Sgr, cast by eclipses of the central binary system. Using geometrical arguments, the degree of flaring of the disk and the distance to the system have been calculated.

    A state-of-the-art magnetohydrodynamic simulation of a solar flare from emergence to eruption is able to reproduce observations at visible, UV and X-ray wavelengths, and suggests that non-thermal particles at high energy may play a less prominent role than usually assumed in flare models.

    Chariklo, Haumea and potentially Chiron are the only known ringed Solar System objects that are not giant planets. The rings of these minor bodies are relatively further from their hosts than those around giant planets; this increase is shown to be due to resonances driven by modest topographic features or elongations.

    A former ALMA prototype antenna has a new lease of life in the harsh conditions of Greenland, where it will play a key role in very-long-baseline interferometry observations of supermassive black holes, explain Nimesh Patel and Paul Ho.

    Volcanic domes are common in our Solar System but so far only one has been identified on dwarf planet Ceres. New research suggests that numerous volcanic domes may have formed throughout Ceres’s history, indicating that cryovolcanism may have once been more common on the dwarf planet.
