Cluster and Double Star observations of dipolarization
We studied two types of dipolarization events with different IMF conditions when Cluster and Double Star (TC1) were located in the same local time sector: 7 August 2004, 18:00–24:00 UT, during a disturbed southward/northward IMF interval, and 14 August 2004, 21:00–24:00 UT, when the IMF was stably northward. Cluster observed dipolarization as well as fast flows during both intervals, but this w...
متن کاملDouble-Star Detection Using Convolutional Neural Network in Atmospheric Turbulence
In this paper, we investigate the usage of machine learning in the detection and recognition of double stars. To do this, numerous images including one star and double stars are simulated. Then, 100 terms of Zernike expansion with random coefficients are considered as aberrations to impose on the aforementioned images. Also, a telescope with a specific aperture is simulated. In this work, two k...
متن کاملPersonal Observations
It is well, and I think timely, that we state publicly our appreciation of men while they are living. It is difficult and perhaps impossible to describe Dr. UWinternitz physically. His features are sharp, his head large, shoulders broad, and as to height, he is on the short side. Not infrequently men with this type of physical make-up are gifted with great drive. That he possesses this characte...
متن کاملConstraints on the Equation of State of Neutron Star Matter From Observations of Kilohertz QPOs
The frequencies of the highest-frequency kilohertz QPOs recently discovered in some sixteen neutron stars in low-mass X-ray binary systems are most likely the orbital frequencies of gas in Keplerian orbit around these neutron stars. If so, these QPOs provide tight upper bounds on the masses and radii of these neutron stars and important new constraints on the equation of state of neutron star m...
متن کاملCoordinated Cluster/Double Star and ground-based observations of dayside reconnection signatures on 11 February 2004
A number of flux transfer events (FTEs) were observed between 09:00 and 12:00 UT on 11 February 2004, during southward and dawnward IMF, while the Cluster spacecraft array moved outbound through the northern, highaltitude cusp and dayside high-latitude boundary layer, and the Double Star TC-1 spacecraft was crossing the dayside low-latitude magnetopause into the magnetosheath south of the eclip...
