Description
Doppler measurements, using the Capri magnetograph, of the latitudinal fine structure of the solar differential rotation have been carried out. The positions of the photospheric lines C I 5380.32 and Fe I 5364.88 have been simultaneously recorded. In contrast to Gilman's model (1972) which predicted an equatorial deceleration of the differential rotation, a minimum of angular velocity is found at a latitude of 6 degrees in both hemispheres.

    Planetary nebula evolution for single stellar models. The formation of neutral spikes
    Two-dimensional hydrodynamical simulations are presented from the formation up to the late evolution of planetary nebula, for six different stellar models from 1 to 5 M $_{\odot }$. The hydrodynamical models use stellar evolution calculations as inner boundary conditions and updated values for the number of ionizing photons. Special emphasis is

    SN 2024bfu, SN 2025qe, and the early light curves of type Iax supernovae
    Type Iax supernovae (SNe Iax) are one of the most common subclasses of thermonuclear supernova and yet their sample size, particularly those observed shortly after explosion, remains relatively small. In this paper, we present photometric and spectroscopic observations of two SNe Iax discovered shortly after explosion, SN 2024bfu and SN 2025qe

    Aligned, Multiple-transient Events in the First Palomar Sky Survey
    Old, digitized astronomical images taken before the human spacefaring age offer a rare glimpse of the sky before the era of artificial satellites. In this paper, we present the first optical searches for artificial objects with high specular reflections near the Earth. We follow the method proposed in Villarroel et al. and use a transient sample
