Astrophysicists at UC Santa Barbara are the first scientists to identify two white dwarf stars in an eclipsing binary system, allowing for the first direct radius measurement of a rare white dwarf ...

Now, a group of astronomers led by Toby Rodel of the Queen's University Belfast, UK, reports the detection of a new system of this type. They detected NGTS-EB-7 AB—a low-mass eclipsing binary ...

However, follow-up observations show that it is a heartbeat system—in particular, a highly eccentric 153-day-period eclipsing binary consisting of a red giant showing solar-like oscillations and ...

TESS previously revealed that Thuban, a former North Star, is also a eclipsing binary, as ... More illustrated here. Three such pairs make up a newly discovered sextuple star system called TYC ...

It’s also known as an eclipsing binary system because one of the stars repeatedly crosses in front of the other. A white dwarf star is the phase in a star’s life cycle when it loses its outer ...

131, No. 997, 2019 March A Detached Eclipsing Binary with a Perio ... the orbital period changes of the binary system are investigated for the first time. We find that the (O − C) (observed-calculated ...

Figure 2: Positions of J0247-25A and J0247-25B in the Hertzsprung–Russell diagram. There is a direct ... made about the evolution of the binary system during the mass transfer episode.

Astrophysicists have identified two white dwarf stars in an eclipsing binary system, allowing for the first direct radius measurement of a rare white dwarf composed of pure helium. Astrophysicists ...
