Descripción
We present the oxygen abundance determination for 90 HII regions in the inner parts of the grand design galaxy M101. The abundances were derived employing the P method (Pilyugin, 2001A&A...369..594P). A comparison is made with previous determinations using another calibration and direct measurements of electron temperature to derive the oxygen abundance. The results show agreement with the abundances derived from the electron temperature method and also show that the older calibration is not as accurate as the P method. (1 data file).

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on
