Irene González Hernández
Irene González Hernández (La Orotava, October 20, 1969-Tucson, February 13, 2014) was a Spanish researcher and astrophysicist, promoter of the development of holographic techniques in local helioseismology, which allow detecting solar activity in the non-visible hemisphere of the Sun. Biography González graduated in physics, specializing in Astrophysics, in 1992 at the University of La Laguna. Subsequently, she obtained an FPI Scholarship to carry out her doctoral thesis at the Instituto de Astrofísica de Canarias (Institute of Astrophysics of the Canary Islands, IAC), within the Solar Seismology Group. Her work was focused on the scientific exploitation of the new high-quality data that the Global Oscillation Network Group project was providing, one of whose instruments, and nodes, was located at the Teide Observatory. Her thesis, titled Synoptic map of transverse flows in the upper layers of the solar convection zone (''Mapa sinóptico de flujos transversales en las cap ...

Photosphere
The photosphere is a star's outer shell from which light is radiated. It extends into a star's surface until the plasma becomes opaque, equivalent to an optical depth of approximately , or equivalently, a depth from which 50% of light will escape without being scattered. A photosphere is the region of a luminous object, usually a star, that is transparent to photons of certain wavelengths. Stars, except neutron stars, have no solid or liquid surface. Therefore, the photosphere is typically used to describe the Sun's or another star's visual surface. Etymology The term ''photosphere'' is derived from Ancient Greek roots, φῶς, φωτός/''phos'', ''photos'' meaning "light" and σφαῖρα/''sphaira'' meaning "sphere", in reference to it being a spherical surface that is perceived to emit light. Temperature The surface of a star is defined to have a temperature given by the effective temperature in the Stefan–Boltzmann law. Various stars have photospheres of vari ...

Women Astrophysicists
A woman is an adult female human. Before adulthood, a female child or adolescent is referred to as a girl. Typically, women are of the female sex and inherit a pair of X chromosomes, one from each parent, and women with functional uteruses are capable of pregnancy and giving birth from puberty until menopause. More generally, sex differentiation of the female fetus is governed by the lack of a present, or functioning, '' SRY'' gene on either one of the respective sex chromosomes. Female anatomy is distinguished from male anatomy by the female reproductive system, which includes the ovaries, fallopian tubes, uterus, vagina, and vulva. An adult woman generally has a wider pelvis, broader hips, and larger breasts than an adult man. These characteristics facilitate childbirth and breastfeeding. Women typically have less facial and other body hair, have a higher body fat composition, and are on average shorter and less muscular than men. Throughout human history, traditi ...

90455 Irenehernandez
9 (nine) is the natural number following and preceding . Evolution of the Hindu–Arabic digit Circa 300 BC, as part of the Brahmi numerals, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. How the numbers got to their Gupta form is open to considerable debate. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an Ascender (typography), ascender ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
