    EX draconis: using eclipses to separate outside-in and inside-out outbursts
    We present a study of the eclipses in the accreting white dwarf EX draconis (EX Dra) during TESS Cycles 14 and 15. During both of the two outbursts present in this data set, the eclipses undergo a hysteretic loop in eclipse-depth/out-of-eclipse-flux space. In each case, the direction in which the loops are executed strongly suggests an outburst

    Dust Environment Model of the Interstellar Comet 2I/Borisov
    2I/Borisov is the first interstellar comet discovered on 2019 August 30, and it soon showed a coma and a dust tail. This study reports the results of images obtained at the Telescopio Nazionale Galileo telescope, on La Palma—Canary Islands, in 2019 November and December. The images have been obtained with the R filter in order to apply our dust

    Doppler tomographic measurement of the nodal precession of WASP-33b
    WASP-33b is a retrograde hot Jupiter with a period of 1.2 d orbiting a rapidly rotating and pulsating A-type star. A previous study found that the transit chord of WASP-33b had changed slightly from 2008 to 2014 based on Doppler tomographic measurements. They attributed the change to orbital precession caused by the non-zero oblateness of the host

    Doppler Imaging and Differential Rotation of σ<SUP>2</SUP> Coronae Borealis Using SONG
    We present new Doppler images of both components of the double-lined binary σ 2 CrB, based on the high-resolution spectroscopic data collected during 11 nights in 2015 March-April. The observed spectra form two independent data sets with sufficient phase coverage. We apply the least-squares deconvolution to all observed spectra to obtain high

    Discovery of a pre-cataclysmic binary with unusual chromaticity of the eclipsed white dwarf by the GPX survey
    We report the discovery of a relatively bright eclipsing binary system, which consists of a white dwarf (WD) and a main-sequence K7 star with clear signs of chromospheric and spot activity. The light curve of this system shows ∼0.2 mag ellipsoidal variability with a period of 0.297549 d and a short total eclipse of the WD. Based on our analysis of

    Cuando la ortodoxia no es lo más relevante: El paisaje de La Gomera y la orientación de sus iglesias
    Presentamos un estudio de la relación entre astronomía y paisaje centrado en la orientación de las iglesias y ermitas cristianas de la isla de La Gomera, situada en el Archipiélago Canario (España). El trabajo de campo consistió en la medición de las coordenadas precisas de ubicación de 38 iglesias y ermitas, lo que representa la casi
