Solar abundances and granulation effects
E. Caffau, H. -G. Ludwig, M. Steffen
The solar abundances have undergone a major downward revision in the last decade, reputedly as a result of employing 3D hydrodynamical simulations to model the inhomogeneous struct…
A solar cycle lost in 1793--1800: Early sunspot observations resolve the old mystery
Ilya G. Usoskin, Kalevi Mursula, Rainer Arlt +1
Because of the lack of reliable sunspot observation, the quality of sunspot number series is poor in the late 18th century, leading to the abnormally long solar cycle (1784--1799)…
Photospheric and chromospheric activity in V405 And: An M dwarf binary with components on the two sides of the full convection limit
K. Vida, K. Oláh, Zs. Kővári +4
We investigate the fast-rotating (P_orb=P_rot=0.465d), active dwarf binary V405 And (M0V+M5V) using photometric BV(RI)_C and optical spectroscopic data. The light variation is caus…
The velocity function in the local environment from LCDM and LWDM constrained simulations
J. Zavala, Y. P. Jing, A. Faltenbacher +4
Using constrained simulations of the local Universe for generic cold dark matter and for 1keV warm dark matter, we investigate the difference in the abundance of dark matter halos…
The QSO HE0450-2958: Scantily dressed or heavily robed? A normal quasar as part of an unusual ULIRG
Knud Jahnke, David Elbaz, Eric Pantin +5
(Abridged) The luminous z=0.286 quasar HE0450-2958 is interacting with a companion galaxy at 6.5 kpc distance and the whole system is a ULIRG. A so far undetected host galaxy trigg…
The contribution of the kinematic Sunyaev-Zel'dovich Effect from the Warm Hot Intergalactic Medium to the Five-Year WMAP Data
Ricardo Genova-Santos, Fernando Atrio-Barandela, Jan Muecket +1
We study the contribution of the kinematic Sunyaev-Zel'dovich (kSZ) effect, generated by the warm-hot intergalactic medium (WHIM), to the cosmic microwave background (CMB) temperat…
