Constraining the core-rotation rate along the red-giant evolution
The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution...
Constraining the dark matter distribution in the centre of early-type barred galaxies
The dynamics of a barred galaxy depends on the pattern speed of its bar. The only direct method for measuring the pattern speed of a bar is the Tremaine...
Constraining the Disk Geometry of Low Mass X-Ray Binaries
We propose to have simultaneously X-ray and optical observations of the two X-ray binaries 4U 1254-69 4U 1916-053 using the rare combination of RXTE and...
Constraining the Initial Mass Function of unresolved stellar populations
All studies of unresolved stellar populations rely on a proper characterization of the stellar initial mass function (IMF), i.e. the distribution of stellar...
Constraining the Orbital Parameters of the Didymos-Dimorphos System: Photometric Observations in Support of DART
The binary near-Earth asteroid (65803) Didymos is the target for the Asteroid Impact and Deflection Assessment (AIDA) concept with two primary spacecraft: NASA...
Constraint on the magnetic moment of the top quark
We derive a bound on the magnetic dipole moment of the top quark in the context of the effective Lagrangian approach by using the ratios Rb=Γb/Γh, Rl=Γh/Γl and...
Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system V577 Oph
We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6 m NOT telescope on La Palma. We have...
