<BR /> Aims: We aim to interpret the photometric and spectroscopic variability of the luminous blue variable supergiant HD 50064 (V = 8.21). <BR /> Methods: CoRoT space photometry and follow-up high-resolution spectroscopy with a time base of 137 d and 169 d, respectively, was gathered, analysed, and interpreted using standard time series analysis and light curve modelling methods, as well as spectral line diagnostics. <BR /> Results: The space photometry reveals one period of 37 d, which undergoes a sudden amplitude change with a factor 1.6. The pulsation period is confirmed in the spectroscopy, which additionally reveals metal line radial velocity values differing by 30 km s[SUP]-1[/SUP] depending on the spectral line and on the epoch. We estimate T[SUB]eff[/SUB] 13 500 K, log g 1.5 from the equivalent width of Si lines. The Balmer lines reveal that the star undergoes episodes of changing mass loss on a time scale similar to the changes in the photometric and spectroscopic variability, with an average value of log dot{M} â -5 (in M_ȯ yr[SUP]-1[/SUP]). We tentatively interpret the 37 d period as the result of a strange mode oscillation. Based on high-resolution spectroscopy assembled with the CORALIE spectrograph attached to the 1.2 m Euler telescope at La Silla, Chile and on CoRoT space-based photometry. The CoRoT space mission was developed and is operated by the French space agency CNES, with the participation of ESA's RSSD and Science Programmes, Austria, Belgium, Brazil, Germany, and Spain.Postdoctoral Fellow of the Fund for Scientific Research of Flanders (FWO), Belgium.

The radial velocity of the magnetic star HD 10783 is shown (fig.2) to vary with the period of the luminosity and magnetic variations. The plot of the magnetic field intensity as a function of the phase (fig.1) gives an asymmetrical curve, which, except for the sign, resembles the luminosity curve, as in other periodic magnetic variables; but the coincidence of the phases remains doubtful. The velocity varies much more rapidly just before the sharper extremum of the magnetic field. [less ▲]

Obestatin has recently been discovered in the rat stomach. As for ghrelin, the 23-amino acid obestatin is also derived from post-translational processing of the prepro-ghrelin gene but seems to have opposite effects on feed intake. In avian species, ghrelin is mainly present in the proventriculus and decreases feed intake, as opposed to its orexigenic properties in mammals. An obestatin-like sequence was also found in the avian ghrelin precursor protein but the potential involvement of this peptide in appetite regulation of chickens is unclear. We therefore investigated the effects of a single peripheral administration of this predicted "chicken" obestatin peptide on voluntary feed intake of 7- to 9-day-old meat-type and layer-type chicks. "Chicken" obestatin was injected intraperitoneally or intravenously at a dose of 1 nmol or 10 nmol/100 g body weight and feed intake was measured up to 4 h post injection. None of these treatments did reveal any effect of the putative "chicken" obestatin on appetite of either meat-type of layer-type chicks. Furthermore, "chicken" obestatin also failed to affect the in vitro contractility of muscle strips from crop and proventriculus. In conclusion, in the given experimental settings, the putative "chicken" obestatin has indistinctive physiological effects on feed intake and in vitro muscle contractility of gut segments, and hence its functional properties in ingestive behavior of avian species remain obscure.
