A Hot Saturn Planet Orbiting Hd 88133, from the N2k Consortium
The N2K consortium is carrying out a distributed observing campaign with the Keck, Magellan and Subaru telescopes, as well as the automatic photometric telescopes of Fairborn Observatory, in order to search for short-period gas giant planets around metal-rich stars. We have established a reservoir of more than 14,000 main sequence and subgiant stars, closer than 110 pc, brighter than Based on o...
متن کاملThe puzzling abundance pattern of HD 134439 and HD 134440 ⋆
Abundances of 18 elements are determined for the common proper-motion pair, HD134439 and HD 134440, which shows high [Mn/Fe] and low [α/Fe] ratios as compared to normal halo stars. Moreover, puzzling abundances are indicated from elements whose origins are normally considered to be from the same nucleosynthesis history. Particularly, we have found that [Mg/Fe] and [Si/Fe] are lower than [Ca/Fe]...
متن کاملHD 139614 , HD 142666 and HD 144432 : evidence for circumstellar disks ?
The morphology of the material surrounding Her-big Ae/Be stars is still a topic of debate. Distinct models with different geometry and optical thickness are found to be compatible with the observed IR excess. This indicates that it is not possible to resolve this question by only looking at the fluxes. Therefore, this paper compares three known Herbig Ae/Be stars with very similar energy distri...
متن کاملResolving the disk rotation of HD 97048 and HD 100546 in the [ O ] 6300 Å line : evidence for a giant planet orbiting HD 100546 ⋆
Aims. We intend to spatially and spectrally resolve the [O ] emission region in two nearby Herbig stars. Methods. We present high-resolution (λ/∆λ = 80,000) VLT/UVES echelle spectra of the [O ] 6300Å line in the Herbig Ae/Be stars HD 97048 and HD 100546. Apart from the spectral signature, also the spatial extent of the [O ] emission region is investigated. For both stars, we have obtained sp...
متن کاملSub-Saturn Planetary Candidates of HD 16141 and HD 46375.
Precision Doppler measurements from the Keck High-Resolution Echelle Spectrograph reveal periodic Keplerian velocity variations in the stars HD 16141 and HD 46375. HD 16141 (G5 IV) has a period of 75.8 days and a velocity amplitude of 11 m s-1, yielding a companion having Msini=0.22 M(JUP) and a semimajor axis of a=0.35 AU. HD 46375 (K1 IV-V) has a period of 3.024 days and a velocity amplitude ...
