Sentences with phrase «teams of astronomers suggest»

In two studies, international teams of astronomers suggest that recent images from NASA's Chandra X-ray Observatory of two pulsars — Geminga and B0355 +54 — may help shine a light on the distinctive emission signatures of pulsars, as well as their often perplexing geometry.

Not exact matches

The team that made this discovery, led by Yale University astronomer Tabetha Boyajian — the star's namesake — suggested a variety of explanations for its strange behavior, including that the star itself was variable, that it was surrounded by clouds of dust or dusty comets, or that planets around it had collided or were still forming.

«Our measurements of the bright spot suggest there are powerful shock waves in the star's atmosphere that reach higher temperatures than are predicted by current theoretical models for AGB stars,» says Theo Khouri, astronomer at Chalmers and member of the team.

However, the band's near - perfect alignment with the Milky Way's disk suggests an alternate theory, says astronomer Annette Ferguson of the University of Groningen, the Netherlands, a member of the Canary Islands team.

At the January 2002, 199th Meeting of the American Astronomical Society in Washington, DC, two teams of astronomers announced that the cold dust in Vega's circumstellar disk is at least partly gathered into large clumps, in a characteristic shape that suggests the gravitational influence of a giant planet in an eccentric orbit (Abstracts for sessions 66.04 and 66.05, and CfA press release).

In 2000, a team of astronomers (Nick N. Gorkavyi, Sara Heap, Leonid Ozernoy, Tanya A. Taidakova, and John Mather) announced that modelling of the asymmetric circumstellar disk infalling into Vega suggests that there may be a planet twice the mass of Jupiter at an orbital distance of about 50 to 60 AU from the star — up to one and a half times the «average» orbital distance of Pluto in the Solar System (N.N. Gorkavyi et al, 2000 and more discussion).

While the mystery of KIC 8462852's brightness variations is still far from settled, a new study by a team of astronomers that has utilised NASA's Spitzer Space Telescope suggests that the culprit is most probably a huge swarm of cometary fragments that revolve around the star on highly elongated eccentric orbits.
