With the high efficieny, high spectral resolution, and high stability,
FEROS at the 1.52-m telescope is well-suited for a large number of
interesting scientific programs, e.g.,
- Search for extra-solar planet systems by monitoring the
radial-velocity variations of the central star. With this
method the first extra-solar planet was discovered around
the sun-like star 51 Peg. Click here to see the measured radial-velocity
curve of 51 Peg.
- Probing the stellar structure and the interiors of stars by methods of
asteroseismology, i.e., measurements of stellar oscillations.
- Determination of chemical abundances in the Galaxy and the
Large and Small Magellanic Clouds using high-resolution spectra
of hot and cool stars.
- Long-term monitoring of hydrodynamic phenomena in hot
stellar atmospheres by following the line-profile variations
of photospheric and wind lines over their characteristic time scales
from hours to months.
- Chromospheric variability of K giant stars by the
simultaneous observation of the CaII H&K, H, and the infrared triplett (IRT) lines.
- Observations of diffuse insterstellar clouds in the
interstellar medium which have a typical velocity seperation
of 6 km/s
- Study of the relation of the dynamics and the ages of
star clusters, which serve as key calibration objects
for the stellar and cosmic age scale.
- Probing the galactic structure by measuring the
radial velocity together with the effective temperature,
surface gravity, and metallicity of A-type stars in the
