From Optical to Chemical Hot Spots in Plasmonics.
Accounts of Chemical Research, 2019 In recent years, the possibility to induce chemical transformations by using tunable plasmonic modes has opened the question of whether we can control or create chemical hot spots in these systems. This can be rationalized as the reactive analogue of the

First solar butterfly diagram from Schwabe's observations in 1825-1867 [PDF]
, 2010 The original sunspot observations by Heinrich Samuel Schwabe of 1825-1867 were digitized and a first subset of spots was measured. In this initial project, we determined more than 14 000 sunspot positions and areas comprising about 11% of the total ...

Properties of starspots on CoRoT-2
, 2009 As a planet eclipses its parent star, a dark spot on the surface of the star may be occulted, causing a detectable variation in the light curve. A total of 77 consecutive transit light curves of CoRoT-2 were observed with a high temporal resolution of 32

Creation of magnetic spots at the neutron star surface [PDF]
, 2014 According to the partially screened gap scenario, an efficient electron-positron pair creation, a general precondition of radio-pulsar activity, relies on the existence of magnetic spots, i.e., local concentrations of strong and small scale magnetic ...
