Discovery of new globular clusters in the Sagittarius dwarf galaxy
(EDP Sciences, 2021-03-12)
Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way. In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important probes of an on-going merger. Aims. Our main goal ...
The Araucaria Project. Infrared Tip of the Red Giant Branch Distances to Five Dwarf Galaxies in the Local Group
(2011)
We have obtained accurate near-infrared photometry of the tip of the red giant branch (TRGB) in the Local Group galaxies Sculptor, NGC 6822, NGC 3109, IC 1613, and WLM. We have used the derived TRGB magnitudes together ...
Rotational velocities for m dwarfs
(2009)
We present spectroscopic rotation velocities (v sin i) for 56 M dwarf stars using high resolution HET HRS red spectroscopy. In addition we have also determined photometric effective temperatures, masses and metallicities ...
Nuevas estrellas pre enanas blancas pulsantes de masa extremadamente baja descubiertas en el CASLEO
(Asociación Argentina de Astronomía, 2016-08)
The Extremely Low Mass white dwarfs (ELM, M 0.18--0.20 M) could arise after the loss of large amount of mass suffered by a red giant star in a binary system. The low mass white dwarfs have become an important source of ...

Effect of nitrogen and application ways of a plant biostimulant on different wheat genotypes contrasting in stature
(2014)
Wheat (Triticum aestivum L.) is the leading crops for human nutrition in Europe and in most temperate regions worldwide. This crop is demanding in nutrients, among them nitrogen (N) is absorbed in higher amounts and its ...
