The population of planets smaller than approximately 1.7 Earth radii (R⊕) is widely interpreted as consisting rocky worlds, generally referred to super-Earths. This picture largely corroborated by radial velocity mass measurements for close-in super-Earths but lacks constraints at lower insolations. Here we present the results a detailed study Kepler-138 system using 13 Hubble and Spitzer trans...

The present study aimed to evaluate the nutritional quality of caferana fruit, focusing on content and profile carotenoids due characteristic coloring these compounds. fruits were collected, botanically identified, evaluated for proximate composition, carotenoid sugar profile, flavonoid profile. results centesimal composition pulp were: 65 g/100g moisture; 0.72 ash; 0.92 protein; 0.78 ethereal ...

Several chromite deposits located in the in the South and Southeast Arms of Sulawesi, Indonesia, have been investigated by electron microprobe. According to the variation of the Cr# = Cr/(Cr + Fe3+), the chromite composition varies from Cr-rich to Al-rich. Small platinum-group minerals (PGM), 1–10 μm in size, occur in the chromitites. The most abundant PGM is laurite, which has been found inclu...

Reflectance spectra of olivines spanning the forsterite-fayalite solid-solution series have been analyzed with the modified Gaussian model (MGM). The compositional variability of the three primary absorption bands that constitute the diagnostic 1.0-gm olivine feature has been quantified by examining the centers, widths, and relative strengths in 18 spectra ranging in composition from Mg-rich fo...
