    Temperature fluctuations in H II regions: Ionization by cosmic rays as a key mechanism
    We present a detailed model capable of explaining quantitatively the temperature fluctuations observed in luminous, large H II regions. The model is based on...

    Temporal albedo variability in the phase curve of KELT-1b
    The dayside brightness spectrum of a highly irradiated transiting brown dwarf KELT-1b is challenging to explain based on current brown dwarf atmosphere models...

    Temporal characteristics of solar p-modes.
    A method for ``time/frequency'' analysis is shortly described, with a discussion of its limitations in time and frequency resolution, and in sensitivity to...

    Temporal evolution of arch filaments as seen in He I 10 830 Å
    Aims: We study the evolution of an arch filament system (AFS) and of its individual arch filaments to learn about the processes occurring in them. Methods: We...

    TESS discovery of two super-Earths orbiting the M-dwarf stars TOI-6002 and TOI-5713 near the radius valley
    We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The...
