Diprotodon on the sky. The Large Galactic Supernova Remnant (SNR) G278.94+1.35
Miroslav D. FilipoviÄ, S. LazareviÄ, M. Araya +41
We present a re-discovery of G278.94+1.35 as possibly one of the largest known Galactic supernova remnants (SNR) - that we name Diprotodon. While previously established as a Galact…
Coronal Structure and Abundances in Young Fast Rotators
D. Garcia-Alvarez, J. J. Drake, V. L. Kashyap +2
AB Dor, Speedy Mic and Rst137B are in their early post-T Tauri evolutionary phase (<100Myr), at the age of fastest rotation in the life of late-type stars. They straddle the corona…
Evidence of the FIP effect in the coronae of late-type giants
D. Garcia-Alvarez, J. J. Drake, B. Ball +2
Cet, 31 Com and Vel represent the main stages through which late-type giants evolve during their lifetime (the Hertzsprung gap (31 Com), the rapid braking zone ( Vel)…
Close to the Dredge: Precise X-ray C and N Abundances in lambda Andromeda and its Precocious RGB Mixing Problem
J. J. Drake, B. Ball, John J. Eldridge +2
Chandra LETG+HRC-S and XMM-Newton RGS spectra of H-like C and N formed in the corona of the lambda And primary star, a mildly metal-poor G8 III-IV first ascent giant that completed…
The Coronae of AB Dor and V471 Tau: Primordial angular momentum vs tidal spin-up
D. Garcia-Alvarez, J. J. Drake, L. Lin +2
The zero-age main-sequence star AB Dor and the K dwarf component of the V471 Tau close binary have essentially identical rotation rates and spectral types. An analysis of their hig…
Exclusive Leptoproduction of Real Photons on a Longitudinally Polarised Hydrogen Target
The HERMES Collaboration, A. Airapetian, N. Akopov +147
Polarisation asymmetries are measured for the hard exclusive leptoproduction of real photons from a longitudinally polarised hydrogen target. These asymmetries arise from the deepl…
