JAXA"s Hayabusa2 is a sample-return mission was launched on Dec. 3, 2014 for bringing back first samples from a C-complex asteroid [1,2]. It arrived at asteroid...

We have known for over three decades that the Sun has depleted its surface lithium. During this period it has become increasingly evident that mixing...

We present the first synthesis of Mn I lines in realistic multi-component magnetized quiet Sun atmospheres, including variation of magnetic field strength...

We report on ongoing study of the Mn-Cr systematics of individual Chainpur (LL3.4) chondrules and compare the results to those for bulk ordinary chondrites...

Mn-Cr data are reported for chondrules from the Bishunpur and Chainpur LL chondrites. It is shown that variations in Mn/Cr for these chondrules were established...

O-type stars display rotational modulation of their photometric brightness due to surface features induced by fossil magnetic fields, and possibly through...

Being relatively rare, the properties of magnetic O stars are not fully understood. To date fewer than a dozen of these stars have been confirmed, making any...

We analyze more than 5000 days of Sun-as-a-star radial velocity GOLF and intensity VIRGO observations to measure the visibilities of the I = 0, 1, 2, and 3...

The Apache Point Observatory Galactic Evolution Experiment (APOGEE) is obtaining high resolution ( 22,500), high signal-to-noise (> 100) spectra in the 1510...
