Tucked away in a star-forming region in the Taurus constellation, a pair of circling stars are displaying some unexpected differences in the circumstellar disks of dust and gas that surround them.

We obtain flux ratios of hydrogen lines for these stars, finding that they have optically thin envelopes, except by 66 Oph and θ CrB, which do not show evidence of a circumstellar disk. γ Cas and ϕ ...

The research suggests that PMOs can form directly through violent interactions between circumstellar disks in young star clusters. PMOs are cosmic nomads, drifting freely through space ...

At first the circumstellar disk is in a phase called an accretion disk, where mass is transported inward toward the star and angular momentum is transported outward. Planet formation likely occurs ...

The star resides in a complex circumstellar environment, which includes a circumstellar disk, accretion streamers, jets and outflows. Previous observations of T CrA have suggested that it may be a ...
