The long orbital period of 78.9 days shows that this is a wide binary system. Gravitational-wave experiments have detected black holes of similar mass, but the formation of such massive ones in a high-metallicity environment would be extremely challenging within current stellar evolution theories. ...
Stellar Classifications of Stars When we are classifying stars into different categories, we do this via two different methods. The first method is the Harvard method; this is done by using the stars surface temperature. The second method is known as the MK method, which we classify stars base...

All light curves, observed and synthetic spectra, RV curve, photometric and synthetic fluxes in the SED, and the stellar/binary evolutionary models used for this work are available from our Zenodo page (https://www.zenodo.org/record/8074854 or https://doi.org/10.5281/zenodo.8074854). Source ...
astronomers immediately applied the notion of two stellar populations to the Galaxy. It is possible to segregate various components of the Galaxy into the two population types by applying both the idea of kinematics of different populations suggested by their position in the Andromeda system and the...
The iOptron SkyGuider Pro is a big step up from the Tracker, offering a heavier payload capacity, a more robust design, and the ability to autoguide your images. TheiOptron SkyGuider Prois a top contender in the category of star trackers withstellar reviewsfrom experienced nightscape photograph...
Such stars drive fast stellar winds where shocks can develop, and it is commonly assumed that the X-rays emerge from the shock-heated plasma. Many massive stars additionally pulsate. However, hitherto it was neither theoretically predicted nor observed that these pulsations would affect their X-...
Frost and Sana's observations were able to piece together this particular stellar jigsaw. One star in a binary system being younger than its companion is a sure sign that a merger of two stars has taken place in the past few thousand years. "We think this system had at least three stars...
