I'm matching the rotational velocity.
The rotational velocity of Beta Pictoris has been measured to be at least 130 km/s.
This is sometimes referred to as the projected rotational velocity.
The measured projected rotational velocity has been measured as high as.
This effect takes place only if the star has low rotational velocity.
Earth's rotational velocity also varies in a phenomenon known as length-of-day variation.
It is spinning rapidly with a projected rotational velocity of 375 km/s.
Rotor rotational velocity is directly proportional to flow rate, since the flow of fluid is causing the rotation.
The derived value is given as formula_1, where"ve" is the rotational velocity at the equator and"i" is the inclination.
However, i is not always known,so the result gives a minimum value for the star's rotational velocity.
It has a projected rotational velocity of 255 km/s, resulting in an equatorial bulge with a radius 13% larger than the polar radius.
Its rotation is very fast, with a projected rotational velocity of 210 km s-1.
The star's projected rotational velocity is 7.0 km/s, corresponding to an inclination angle of about 60°.
It has the spectroscopic signature of a rapidly rotating star, with a projected rotational velocity of about 66 km s-1.
Gamma Arae is rotating rapidly with a projected rotational velocity of 269 km s-1, causing it to complete a full rotation about every 4.8 days.
Using the stellar spectrum, astronomers can also determine the surface temperature, surface gravity,metallicity and rotational velocity of a star.
Because the primary component is spinning rapidly with a projected rotational velocity of, it is difficult to obtain reliable orbital elements.
Its effect is much smaller than that of annual aberration, and is only 0′′.32 in the case of an observer at the equator,where the rotational velocity is greatest.
The region outside the event horizon butinside the surface where the rotational velocity is the speed of light, is called the ergosphere from Greek ergon meaning work.
Its effect is much smaller than that of annual aberration, and is only 0.32 arcseconds in the case of an observer at the Equator,where the rotational velocity is greatest.
For the rotational diagnostic,we use projected rotational velocity computed from observations carried out with of the coravel spectrometers baranne et al.
If there were transfer of angular momentum from the Sun's orbit to the spin on its axis,this would make a difference of up to 7% in its equatorial rotational velocity Blizard, 1982.
Variations of more than 7% in the sun's equatorial rotational velocity, going along with variations in solar activity, were observed at irregular intervals Landscheidt, 1976, 1984.
The derived value is given as v e⋅ sin i{\displaystyle v_{e}\cdot\sin i},where ve is the rotational velocity at the equator and i is the inclination.
For example, as the Earth's rotational velocity is 465 m/s at the equator, a rocket launched tangentially from the Earth's equator to the east requires an initial velocity of about 10.735 km/s"relative to Earth" to escape whereas a rocket launched tangentially from the Earth's equator to the west requires an initial velocity of about 11.665 km/s"relative to Earth.
The star is radiating 132 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,316 K. The projected rotational velocity is too small to be measured.
The pioneering work proposed by skumanich(1972) has shown that the projected mean rotational velocity< v sini> for solar type stars follows a rotation law decreases with the time given by t¿1=2, where t is the stellar age.
The study physical process that control the stellar evolution is strength influenced by several stellar parameters, like as rotational velocity, convective envelope mass deepening, and magnetic field intensity.
This is because approximately fourEarth days before perihelion, Mercury's angular orbital velocity equals its angular rotational velocity so that the Sun's apparent motion ceases; closer to perihelion, Mercury's angular orbital velocity then exceeds the angular rotational velocity. .
In this study we analyzed the interconnection of some stellar parameters, as lithium abundance a(li), chromospheric activity andmagnetic field intensity as well as the variation of these parameters as a function of age, rotational velocity, and the convective envelope mass deepening for a selected sample of solar analogs and twins stars.
