Balloon 090100001 has turned out to be one of the most interesting pulsating sdB stars. However, its interest compares with the difficulty for it to be modelled. We present some clues or strategies from which some information can be inferred based on a comparison between observed and theoretical frequencies alone. These strategies might be applied

For a long time, radio-loud Broad Absorption Line Quasars (BAL QSOs) were thought to be extremely rare objects. The absorbing troughs seen in their optical spectra are due to strong winds which probably have their origin within the inner region of the AGN, as a result of the accretion processes. Their radio emission constitutes an additional

Many talks in this conference have shown the power of high resolution spectroscopy, coupled to high precision. A new spectrograph, fed by an Extremely Large Telescope, will have such a huge collecting power that it will allow for the first time some outstanding applications. We argue here that such a new instrument should therefore aim at the

If we were to observe the light reflected from an extrasolar planet, the portion of the planet reflecting starlight toward us would change due to rotation and orbital motion. Reflected light will come from the planet's surface, but also from the clouds and atmosphere. It is possible that these two planetary components have different rotation speeds

In the future, new robotic missions will be launch toward Mars with the objective of studying this planet from its surface. Phoenix (2007), Mars Science Laboratory (2009), Mars Sample Return, ExoMars, Astrobiological Field Laboratory or the Deep-drill lander (beyond 2009) are the missions already launched, approved or under planning by NASA for the
