The mass distributions derived from transiting planets is preliminary and can be updated after the RV follow-up of K2 planets will be more complete and the number of Kepler 1 confirmed planets definitive. The significances of the local minima (plateau) in the retrieved mass distribution have ...

Quasi-stationary planetary waves exhibit different seasonal behaviour in the two winter stratospheres. Whereas, in a climatological sense, wave amplitudes ... RA Plumb - 《Pure & Applied Geophysics》 被引量: 91发表: 1989年 Far Ultraviolet Spectroscopic Explorer Observations of Possible Infalling Plane...
We then compare the seismic masses of the full ensemble of 16 stars with the spectroscopic masses from three different literature sources. We find an offset between the seismic and spectroscopic mass scales that is mass-dependent, suggesting that the previously claimed overestimation of spectroscopic ...
of CH4in solar system giant planets, where CH4abundance, unlike H2O, is unaffected by condensate cloud formation. However, all of the solar system giants exhibit some evidence for stratification of metals outside of their cores. In this context, two fundamental questions are whether metallicity of...
How are weight and mass different? Mass is the amount of matter in an object. Weight is the downward force acting upon an object due to gravity. On planet Earth, the two quantities are proportional. What is the relationship between mass and weight of an object? Mass and weight, on a gi...
This type of analysis results in a variety of different expressions for the minimum fragmentation mass, depending on the assumptions. If we find the point where a gas parcel contains one Jeans mass, has optical depth unity, and can radiate away is energy of self-gravity on a free-fall time...
<italic>Context.</italic> Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of planet candidate
Aims.We aim at investigating correlations between the host star’s mass and the presence of wide-orbit giant planets, and at providing new observational constraints on planetary formation models. Methods.We observed 58 young and nearby M-type dwarfs inL′-band with the VLT/NaCo instrument and ...
Mass of Planets: The most accurate way of measuring mass of a planet is to send a spacecraft to it and measure the acceleration due to gravity as the spacecraft passed by it. Alternatively, if the planet has a moon, then it's mass can be calculated from the moon's...
