Observations of Baily beads in French Guyana, during 2006 September 22 annular eclipse, have been made to measure solar radius around solar minimum activity of cycle 23. The correction to standard solar radius at unit distance (1 AU) 959.63" to fit observations isΔR⊙= -0.01" ± 0.17". ...
The past tidal heating of each planet may have contributed significantly to the thermal budget that governed the planet's physical properties, including its radius, which in many cases may be measured by observing transit events. Here we also compute the plausible heating histories for a few ...
The nonideal region is assumed to be in the form of a cylindrical tube with height \(L_z\) and radius \(r_c\) (Fig. 4d). A loop integral of the electric field around the tube under Faraday’s law will allow us to replace \(L_zE_z\) with \(-r_cE_r\). We can then ...
Thus, even though this layer corresponds to only about 3% of the solar radius, and only about 10% of the geometrical depth of the solar convection zone, mass density and pressure vary by factors of about 105 and 106 across it, respectively. Figure 1: Schematic figure showing the average ...
Current IACT arrays are capable of detecting objects smaller than 100m in radius in the Kuiper Belt and 1km radius out to 5000?au. The future Cherenkov Telescope Array (CTA) will have even greater capabilities. Because the arrays include several telescopes, they can potentially measure the ...
(Al2O3). The metal thickness of the composite disk structure is H4 = 45 nm and the dielectric thickness is H5 = 30 nm. Our absorbing disk has a radius of R1 = 160 nm, R2 = 120 nm, and R3 = 80 nm, and its structural period is P = 400 nm, as shown inFigure 1a,b. The ...
Around a million quasars have been catalogued in the Universe by probing deeper and using new methods for discovery. However, the hardest ones to find seem to be the rarest and brightest specimens. Here we study the properties of the most luminous of all quasars found so far. These have ...
First, there is significant distortion of the CME in the interplanetary medium. By 1 AU the CME has effectively separated (in radius as well as latitude) into two pieces. The radial separation is due to the strong velocity shear between the slow and fast ambient solar wind. The latitudinal ...

solar radius variations (see reviews by Solanki et al.2005; Lockwood2010). Larger percentage variations are seen in solar UV emissions (Lean et al.1997) which arise from the lower solar atmosphere (the chromosphere) (Loukitcheva et al.2009) and which influence the stratosphere in Earth’s ...
