Very Luminous Carbon Stars in the Outer Disk of the Triangulum Spiral Galaxy
D. L. Block, K. C. Freeman, T. H. Jarrett +4
Stars with masses in the range from about 1.3 to 3.5 Mo pass through an evolutionary stage where they become carbon stars. In this stage, which lasts a few Myr, these stars are ext…
Encircling an Exceptional Point
C. Dembowski, B. Dietz, H. -D. Graef +4
We calculate analytically the geometric phases that the eigenvectors of a parametric dissipative two-state system described by a complex symmetric Hamiltonian pick up when an excep…
A relativistic helical jet in the gamma-ray AGN 1156+295
X. Y. Hong, D. R. Jiang, L. I. Gurvits +7
We present the results of a number of high resolution radio observations of the AGN 1156+295. These include multi-epoch and multi-frequency VLBI, VSOP, MERLIN and VLA observations…
