This image is of V1025 Tauri, a triple star system in the Taurus Molecular Cloud some 400-450 light years away; its Gaia EDR3 is 788 ly but that seems unlikely. The photographer noticed some faint nebulosity around the star, took a chance, and ended up with this picture--as an object it is virtually unstudied, with only one other widely available picture that I'm aware of. (1/2)

Now is time for the spectrum of a Wolf-Rayet type of star: WR-7 also catalogued as V1687 Cyg.
It is a WC, meaning that it is a star rich in carbon. We can actually "see" the carbon and helium inner layers, because the intense stellar winds and a pronounced unstable hydrostatic equilibrium have expelled its outer hydrogen layers to interstellar space. The broad emission lines are trademark of these types of stars.

Before the end 2022 (according to my time zone), allow me to share a final light curve for the rotational variable Star HD 251108.

These observations we're requested by the AAVSO in their Variable Alert #798.

May this domingo 2023 be full of amazing #astronomy discoveries, fun, and awe!

#variablestar

First post in this network! Light curves for HD 251108, in response to AAVSO's Alert 798.

Data obtained with @lco 0m4 telescopes at Siding Spring & Teide observatories, and processed with Astrosource (Fitzgerald et al)

Observations are still in progress.
