Geodesics dynamics in the Linet-Tian spacetime with Lambda>0
Irene Brito, M. F. A. Da Silva, Filipe C. Mena +1
We analyse the geodesics' dynamics in cylindrically symmetric vacuum spacetimes with Lambda>0 and compare it to the Lambda=0 and Lambda<0 cases. When Lambda>0 there are two singula…
Period spacings in red giants; III. Coupling factors of mixed modes
B. Mosser, C. Pinçon, K. Belkacem +2
The power of asteroseismology relies on the capability of global oscillations to infer the stellar structure. For evolved stars, we benefit from unique information directly carried…
A model for stealth coronal mass ejections
B. J. Lynch, S. Masson, Y. Li +4
Stealth coronal mass ejections (CMEs) are events in which there are almost no observable signatures of the CME eruption in the low corona but often a well-resolved slow flux rope C…
First scattered-light images of the gas-rich debris disk around 49 Ceti
É. Choquet, J. Milli, Z. Wahhaj +31
We present the first scattered-light images of the debris disk around 49 ceti, a ~40 Myr A1 main sequence star at 59 pc, famous for hosting two massive dust belts as well as large…
In and out star formation in z~1.5 quiescent galaxies from rest-frame UV spectroscopy and the far-infrared
Raphael Gobat, Emanuele Daddi, Veronica Strazzullo +18
We present a sample of 34 spectroscopically confirmed BzK-selected ~1e11 Msun quiescent galaxies (pBzK) in the COSMOS field. The targets were initially observed with VIMOS on the V…
Measurement of the CKM angle from a combination of LHCb results
LHCb collaboration, R. Aaij, B. Adeva +765
A combination of measurements sensitive to the CKM angle from LHCb is performed. The inputs are from analyses of time-integrated , $B^{0} \rightarrow D K…
