    The entropy of galaxy spectra
    The ability of any Machine Learning method to classify the spectra of galaxies depending on the properties of the stellar component rests on the information...

    The entropy of galaxy spectra: how much information is encoded?
    The inverse problem of extracting the stellar population content of galaxy spectra is analysed here from a basic standpoint based on information theory. By...

    The First Extrasolar Planet Discovered with a New-Generation High-Throughput Doppler Instrument
    We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new-generation Doppler instrument. The planet...

    The first measurements of carbon isotopic ratios in post-RGB stars: SZ Mon and DF Cyg
    Dusty post-red giant branch (post-RGB) stars are low- and intermediate-mass stars where the RGB evolution was prematurely terminated by a poorly understood...

    The first planet detected in the WTS: an inflated hot Jupiter in a 3.35 d orbit around a late F star
    We report the discovery of WTS-1b, the first extrasolar planet found by the WFCAM Transit Survey, which began observations at the 3.8-m United Kingdom Infrared...

    The first release of data from the Herschel ATLAS: the SPIRE images
    We have reduced the data taken with the Spectral and Photometric Imaging Receiver (SPIRE) photometer on board the Herschel Space Observatory in the Science...

    The first spectroscopically identified L dwarf in Praesepe
    We have obtained a low-resolution optical spectrum for one of the faintest cluster member candidates in Praesepe with the Optical System for Imaging and low...

    The first super-Earth detection from the high cadence and high radial velocity precision Dharma Planet Survey
    The Dharma Planet Survey (DPS) aims to monitor about 150 nearby very bright FGKM dwarfs (within 50 pc) during 2016-2020 for low-mass planet detection and...
