    A high-resolution study of the structure of sunspot light bridges and abnormal granulation
    Strong light bridges (SLBs) represent an abrupt change in the physical conditions of sunspot umbrae. They divide the umbra into separate units (fragments...

    A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO
    Context. Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected...

    A possible nineteen-minute periodicity in the light curve of OJ 287
    A periodic signal of high nominal significance (99.95 percent) is found in the light curve of OJ 287 in observations taken with the Prime Focus Camera Unit on...

    A proposal for a low instrumental polarization coude telescope
    A technique for obtaining an ideal two-mirror coude system with no instrumental polarization is described. A half-wave plate positioned between the two mirrors...

    A proposal for a low instrumental polarization coude telescope. II. The German Gregory-Coude Telescope at the Observatorio del Teide.
    We have put into practice the technique to minimize the instrumental polarization (IP) of coude telescopes proposed by Martinez Pillet & Sanchez Almeida (1991)...

    A retrospective of the GREGOR solar telescope in scientific literature
    In this review, we look back upon the literature, which had the GREGOR solar telescope project as its subject including science cases, telescope subsystems, and...
  • Publication
    A search for solar-like oscillations in the stars of M67 with CCD ensemble photometry on a network of 4 M telescopes
    Results are presented from a large observational project directed toward the detection of solar-like oscillations in an ensemble of open cluster stars. Seven...
