The accretion picture of Cen X-3 as inferred from one month of continuous X-ray observations.

van der Klis, M.; Bonnet-Bidaud, J. M.

COS-B X-ray observations of Cen X-3 in December 1975 include a turn-on of the source and a high state extending over the rest of the observation period, during which a clear transition in intensity occurs. These data are used to show that the accretion picture of Cen X-3 is reconcilable with a stellar wind only by taking the most extreme assumptio…

Gas, dust, high energy particles and star formation in the Galactic Center

Puget, J. -L.; Lequeux, J.; Audouze, J. +1 more

The amount of gas and dust in the Galactic Center is evaluated. The COS-B and SAS-2 gamma-ray observations of the Galactic Center are discussed and limits for the flux of high-energy cosmic rays are derived from them. Consideration is given to low-energy cosmic rays which are indirectly responsible via their interaction of the interstellar matter,…
