The Citation Impact of Digital Preprint Archives for Solar Physics Papers [PDF]

, 2006
Papers that are posted to a digital preprint archive are typically cited twice as often as papers that are not posted. This has been demonstrated for papers published in a wide variety of journals, and in many different subfields of astronomy.

X-ray bursting neutron star atmosphere models using an exact relativistic kinetic equation for Compton scattering [PDF]

, 2012
Theoretical spectra of X-ray bursting neutron star (NS) model atmospheres are widely used to determine the basic NS parameters such as their masses and radii.

Dynamical Interactions and the Black Hole Merger Rate of the Universe [PDF]

, 2007
Binary black holes can form efficiently in dense young stellar clusters, such as the progenitors of globular clusters, via a combination of gravitational segregation and cluster evaporation.

Multi-epoch, high spatial resolution observations of multiple T Tauri systems [PDF]

, 2017
Context. In multiple pre-main-sequence systems the lifetime of circumstellar disks appears to be shorter than around single stars, and the actual dissipation process may depend on the binary parameters of the systems. Aims.
