X-ray determination of the variable rate of mass accretion onto TW hydrae

Mostrar todas las versiones(2)

Diagnostics of electron temperature (Te), electron density (ne), and hydrogen column density (N H) from the Chandra High Energy Transmission Grating spectrum of He-like Ne IX in TW Hydrae (TW Hya), in conjunction with a classical accretion model, allow us to infer the accretion rate onto the star di...
