Eclipsing damped Ly α systems in the Sloan Digital Sky Survey Data Release 12★ Open

H. Fathivavsari, P. Petitjean, N. Jamialahmadi, Habib G. Khosroshahi, H. Rahmani , et al. · 2018

We present the results of our automatic search for proximate damped\nLy$\\alpha$ absorption (PDLA) systems in the quasar spectra from the Sloan\nDigital Sky Survey Data Release 12. We constrain our search to those PDLAs\nlying within 1500 …

On the inner disc structure of MWC480: evidence for asymmetries? Open

N. Jamialahmadi, B. López, P. Berio, A. Matter, S. Flament , et al. · 2017

Studying the physical conditions structuring the young circumstellar disks is\nrequired for understanding the onset of planet formation. Of particular\ninterest is the protoplanetary disk surrounding the Herbig star MWC480. The\nstructure …

Une étude multi longueur d’onde des disques protoplanétaires à l’échelle de l’unité astronomique Open

N. Jamialahmadi · 2015

Planetary systems are born in circumstellar gas and dust disks surrounding Young Stellar Objects (YSOs). To understand how planetary systems form, a detailed knowledge of the structure and evolution of these disks is required. Although, th…

The peculiar fast-rotating star 51 Ophiuchi probed by VEGA/CHARA Open

N. Jamialahmadi, P. Bério, A. Meilland, K. Perraut, D. Mourard , et al. · 2015

\n Context. Stellar rotation is a key in our understanding of both mass-loss and evolution of intermediate and massive stars. It can lead to anisotropic mass-loss in the form of radiative wind or an excretion disk.\n Aims. We wished to spa…
