Description
A photometric analysis is conducted of the open cluster NGC 7044, on the basis of UBVR CCD observations of 896 stars in the cluster field. Reddening and metallicity estimates are highly dependent on whether reddening slopes and absorption coefficients vary with spectral type. The color-magnitude diagram obtained is compared with selected sets of isochones, based on evolutionary models computed with and without consideration of convective overshooting from the stellar core during the H and He phases of core burning. Better general agreement is obtained between predicted and observed features of the color-magnitude diagram with overshooting models.

    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
