The Astronomical Marvel of WR 134
Nestled within the star-studded canvas of the Cygnus constellation, 6,000 light-years from us, lies the enigmatic Wolf-Rayet star, WR 134, alternatively known as V1769 Cygni and BD+35°4001. A proud member of the Cygnus OB3 stellar association, WR 134 commands the attention of the astronomical community.
Stellar Brilliance Encased in a Cosmic Bubble
This variable star, cradled in a delicate cosmic bubble, is a living testament to the mighty stellar wind that effuses from its core. Boasting a mass that equals 18 suns, a blistering temperature of 63,000 Kelvin, and a luminosity that outshines the Sun by 400,000 times, the magnificence of WR 134 is truly unparalleled.
The Historical Legacy of Wolf-Rayet Stars
Wolf-Rayet (WR) stars first made their celestial debut in 1867, courtesy of astronomers Charles Wolf and Georges Rayet. Among these cosmic marvels, WR 134, alongside WR 135 and WR 137, has etched an indelible mark on the annals of astronomical history.
The Spectral Dance of WR 134
A careful examination of WR 134's spectrum unveils a captivating performance of ionised nitrogen, helium, and carbon emission lines. The star's variable nature adds a layer of intrigue, showcasing brightness oscillations over hours to days, albeit devoid of strict periodicity.
The X-ray Emission Paradox
Adding to its mystique, WR 134 emits X-rays. Yet, its complex emission profile defies conventional astrophysical rationale, challenging the expectations of a lone star. The improbable existence of a dense source, such as a neutron star, or colliding stellar winds, only amplifies the cosmic conundrum.
Capturing the Celestial Beauty
Through the lens of an ardent amateur astronomer, Jose Luis Bedmar, the composite optical image of WR 134 comes alive. The image masterfully merges broadband filters (RGB) with narrow-band filters, accentuating the hypnotic gleam of doubly ionised oxygen ([O III]) and ionised hydrogen (Hα).
