Sub-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 ...
متن کاملTrojan Pairs in the Hd 128311 and Hd 82943 Planetary Systems?
Two nearby stars, HD 128311 and HD 82943, are believed to host pairs of Jupiter-like planets involved in a strong first order 2:1 mean motion resonance. In this work we reanalyze available radial velocity (RV) measurements and demonstrate that it is also possible to explain the observed RV variations of the parents stars as being induced by a pair of Trojan planets. We show that these Trojan co...
متن کاملThe Spectroscopic Orbital Period of Hd 45166
HD 45166 was selected as a candidate to the V Sagittae Class. It’s spectrum shows quite narrow emission lines of He, C, N, and O, possibly indicating a low inclination for the binary system. We performed high resolution and high stability Coudé spectroscopy in order to search for low amplitude radial velocity variations. The orbital period determined from the radial velocity curve is 0.357 days...
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 کاملHD 209458 planetary transits from Hipparcos photometry ?
During its 39-month mission, Hipparcos observed the star HD 209458 on 89 occasions. Five of these observations are shown to correspond to epochs of planetary transits, with a 2.3 ± 0.4% mean decrease of flux in the Hp band being observed during the transits. As a result of the long temporal baseline of more than 8 years between the Hipparcos and radial velocity measurements, an accurate orbital...
