The spatially-resolved information provided by these observations are allowing us to test and extend the previous body of results from small-sample studies, while at the same time

Second, the sample of less massive (M  ≤ 1.5 M  ) giant stars with planets covers the same mass range as the MS pro- genitors and subgiant stars where the metal signature has

Plotinus draws on Plato’s Symposium (206c4–5) – “procreate in what is beautiful” – 3 in order to affirm that mixed love (which is also a love of beauty) is fecund, although

Although some public journalism schools aim for greater social diversity in their student selection, as in the case of the Institute of Journalism of Bordeaux, it should be

In the “big picture” perspective of the recent years that we have described in Brazil, Spain, Portugal and Puerto Rico there are some similarities and important differences,

The high eccentricity of the planet is uncommon among planetary systems orbiting evolved stars and so is the high lithium abundance in a giant starM. The ingestion by the star of

The cornerstone of the suspicion of a chiral phase transition is the singular behavior of the quark condensate < q ¯ q >, since this expectation value is an order parameter
