Abstract (EN): The radiation emitted by accelerated fundamental strings and D-branes is studied within the linear approximation to the supergravity limit of string theory. We show that scalar, gauge field and gravitational radiation is generically emitted by such branes. In the case where an external scalar field accelerates the branes, we derive a Larmor-type formula for the emitted scalar radiation and study the angular distribution of the outgoing energy Aux. The classical radii of the branes are calculated by means of the corresponding Thompson scattering cross sections. Within the Linear approximation, the interaction or the external scalar field with the velocity fields of the branes gives a contribution to the observed gauge field and gravitational radiation.
