The View from Out There<p>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.

Enrique Boeneker<p>Now is time for the spectrum of a Wolf-Rayet type of star: WR-7 also catalogued as V1687 Cyg.<br>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.<br><a href="https://astrodon.social/tags/Astrodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Astrodon</span></a> <a href="https://astrodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>astronomy</span></a> <a href="https://astrodon.social/tags/spectra" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>spectra</span></a> <a href="https://astrodon.social/tags/spectroscopy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>spectroscopy</span></a> <a href="https://astrodon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>science</span></a> <a href="https://astrodon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>space</span></a> <a href="https://astrodon.social/tags/stars" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>stars</span></a> <a href="https://astrodon.social/tags/variablestar" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>variablestar</span></a></p>
