    A Planetary Nebula around Nova V458 Vulpeculae Undergoing Flash Ionization
    Nova V458 Vul erupted on 2007 August 8 and reached a visual magnitude of 8.1 a few days later. Hα images obtained 6 weeks before the outburst as part of the...

    A planetary system with two transiting mini-Neptunes near the radius valley transition around the bright M dwarf TOI-776
    We report the discovery and characterization of two transiting planets around the bright M1 V star LP 961-53 (TOI-776, J = 8.5 mag, M = 0.54 ± 0.03 M ☉)...

    A Planetary-Mass Companion to the K0 Giant HD 17092
    We report the discovery of a substellar-mass companion to the K0 giant HD 17092 with the Hobby-Eberly Telescope. In the absence of any correlation of the...

    A planetesimal orbiting within the debris disc around a white dwarf star
    Many white dwarf stars show signs of having accreted smaller bodies, implying that they may host planetary systems. A small number of these systems contain...

    A plausible link between dynamically unsettled molecular gas and the radio jet in NGC 6328
    We report the detection of outflowing molecular gas at the center of the nearby radio galaxy NGC6328 (z = 0.014), which has a gigahertz-peaked spectrum radio...
  • Publication
    A Pluto-like radius and a high albedo for the dwarf planet Eris from an occultation
    The dwarf planet Eris is a trans-Neptunian object with an orbital eccentricity of 0.44, an inclination of 44 degrees and a surface composition very similar to...

    A polarization model for the German Vacuum Tower Telescope from in situ and laboratory measurements
    It is essential to properly calibrate the polarimetric properties of telescopes, if one wants to take advantage of the capabilities of high precision spectro...

    A Polarized Accretion Disk Flare in OJ:287
    A very rapid swing in the polarization position angle (PA) in the optical region was observed in blazar OJ 287 during one night of our five nights UBVRI...

    A polarized fast radio burst at low Galactic latitude
    We report on the discovery of a new fast radio burst (FRB), FRB 150215, with the Parkes radio telescope on 2015 February 15. The burst was detected in real time...
