The Monkey Head Nebula
======================

NGC 2175 is a glowing star-forming region in Orion, about 6.400 light-years away. It belongs to the wider Sh2-252 complex (often discussed alongside NGC 2174) and spans a surprisingly large patch of sky.

Powered by the hot O-type star HD 42088, ultraviolet light makes hydrogen shine while dark dust lanes carve the familiar “monkey” silhouette. A stellar nursery in motion, shaped by radiation and winds as new stars emerge.

Discover Orion: The Hunter in the Night Sky 🌌

Orion is one of the most recognizable constellations, visible from both hemispheres. Named after the legendary hunter from Greek mythology, it dominates the winter sky in the Northern Hemisphere and the summer sky in the Southern Hemisphere.

The evolutionary stage of Betelgeuse inferred from its pulsation periods

Betelgeuse is a well known bright red supergiant that shows semi-regular variations with four approximate periods of 2200, 420, 230, and 185 days. While the longest period was customarily regarded as LSP (long secondary period) of unknown origin, we identify the ~2200-d period as the radial fundamental mode, and the three shorter periods as the radial first, second, and third overtones. From a nonadiabatic pulsation analysis including the pulsation/convection coupling, we have found that these radial pulsation modes are all excited in the envelope of a model in a late stage of the core-carbon burning. Models with similar pulsation property have masses around 11M_\odot (19M_\odot at ZAMS) with luminosities (log L/L_\odot =5.27~5.28) and effective temperatures (log T_{eff}\approx 3.53) that are consistent with the range of the observational determinations. We also find that a synthetic light curve obtained by adding the fundamental and the first-overtone mode qualitatively agrees with the light curve of Betelgeuse up to the Great Dimming. We conclude that Betelgeuse is in the late stage of core carbon burning, and a good candidate for the next Galactic supernova.

Got another nice look at #OrionConstellation right now, and the skies seem to remain clear tonight. Look forward to losing myself in the Nebulosities of Orion later on.
