    An Ultra-hot Low-mass Brown Dwarf Eclipsing the Puffy White Dwarf J0404+1112
    Most exoplanets known orbit stars that will evolve into red giants, then white dwarfs (WDs). Understanding the population of substellar WD companions informs...

    An Unbiased Survey of X-ray and Optical Emission from Extended Radio Jets in AGN with Chandra and HST
    The Chandra discovery of an X-ray bright jet in the "first light" distant quasar PKS 0637-752 showed that the X-rays can be energetically dominant even at large...

    An UXor among FUors: extinction-related brightness variations of the young eruptive star V582 Aur
    The early evolution of Sun-like stars may be interspersed by energetic FU Orionis (FUor) type accretion outbursts. We analysed eight years of photometric and...
