    The binary fraction of planetary nebula central stars - III. the promise of VPHAS+
    The majority of planetary nebulae (PNe) are not spherical, and current single-star models cannot adequately explain all the morphologies we observe. This has...

    The binary millisecond pulsar PSR J1023+0038 - II. Optical spectroscopy
    We present time-resolved optical spectroscopy of the `redback' binary millisecond pulsar system PSR J1023+0038 during both its radio pulsar (2009) and accretion...
  • Publication
    The binary millisecond pulsar PSR J1023+0038 during its accretion state - I. Optical variability
    We present time-resolved optical photometry of the binary millisecond `redback' pulsar PSR J1023+0038 (=AY Sex) during its low-mass X-ray binary phase. The...

    The black hole population in low-mass galaxies in large-scale cosmological simulations
    Recent systematic searches for massive black holes (BHs) in local dwarf galaxies led to the discovery of a population of faint active galactic nuclei (AGNs). We...

    The black hole transient Nova Scorpii 1994 (=GRO J1655-40): orbital ephemeris and optical light curve
    We have measured the brightness of the optical counterpart of the black hole X-ray binary Nova Sco 1994 (GRO J1655-40) during 40 nights between 1995 May 3 and...

    The black widow pulsar J1641+8049 in the optical, radio, and X-rays
    PSR J1641+8049 is a 2 ms black widow pulsar with the 2.2 h orbital period detected in the radio and γ-rays. We performed new phase-resolved multiband photometry...

    The blue supergiant Sher 25 and its intriguing hourglass nebula
    The blue supergiant Sher25 is surrounded by an asymmetric, hourglass-shaped circumstellar nebula. Its structure and dynamics have been studied previously...

    The breakdown of current gyrochronology as evidenced by old coeval stars
    Gyrochronology can yield useful ages for field main-sequence stars, a regime where other techniques are problematic. Typically, gyrochronology relations are...
