Installation of Solar Chromospheric Telescope at the Indian Astronomical Observatory, Merak
Ravindra B, Prabhu Kesavan, Thulasidharen +13
We report the observations of the solar chromosphere from a newly commissioned solar telescope at the incursion site near Pangong Tso lake in Merak (Leh/Ladakh). This new H te…
Half-lives of neutron-rich Cd
Dunlop, R., Bildstein +69
The -decay half-lives of Cd have been measured with the newly commissioned GRIFFIN -ray spectrometer at the TRIUMF-ISAC facility. The time structures of…
Doppler images of the RS CVn binary II Pegasi during the years 1994-2002
Lindborg, M., Korpi +8
We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. The six maps from 1999-2002 are based on previously unpublished observation…
Discovery of a Metal-poor, Luminous Post-AGB Star that Failed the Third Dredge-up
D. Kamath, H. Van Winckel, P. R. Wood +4
Post-asymptotic giant branch (post-AGB) stars are known to be chemically diverse. In this paper we present the first observational evidence of a star that has failed the third dred…
