Descripción
RXTE PCA Bulge scans detected activity of what appeared to be a known source. However, based on the results presented below, and the report of a new INTEGRAL source IGR J17511-305 (Baldovin et al. ATEL #2196), the activity detected by RXTE is due to a new 245 Hz X-ray pulsar. The source was initially detected on 2009-09-11 at 17:50 UT as a rising flux attributed to two known sources, XTE J1751-305 and GRS 1747-312, the first of which is a known 435 Hz X-ray pulsar.

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
