The Physics and Astronomy Institute (IFA) of the University of Valparaiso offers undergraduate and graduate degrees in Physics and Astronomy. Its vibrant community of faculty, research staff and students works on a wide range of topics in physics and astronomy while carrying out an ambitious Outreach Program for the astronomical sciences. We are permanently stimulated by the close and collaborative relationship of the Institute with the Center for Astrophysics of Valparaíso, CAV, who permanently dictate Seminars for the benefit of our Undergraduate and postgraduate students.

El Instituto de Física y Astronomía recibió ayer martes, 15 de Abril 2014, al Dr. Thomas Henning, Director del Instituto Max Planck para la Astronomía, quien dictó un Seminario Astrofísico titulado "From Protoplanetary Disks to Extrasolar Planetary Systems", para los miembros del Instituto, Postdocs, y alumnos del Magister y Doctorado en Astrofísica. Su excelente, interesante y amena exposición llevó a un nutrido intercambio de comentarios y, mas importante, a una intensa sesión de preguntas que fueron respondidas por el Dr. Henning, quien proviene de una de las mas prestigiosas instituciones dedicadas a la investigación y publicación de papers científicos en mas de un área de la ciencia. Esta visita estrecha lazos entre el IFA y el Instituto Max Planck para visitas futuras que estimulen la investigación y colaboración en áreas de interés teórico y observacional. [Abril 16, 2014]
The Institute for Physics and Astronomy, headed by its Director, Dr. Michel Curé, is pleased to announce that its Postgraduate Program, Master in Astrophysics, has been accredited until March 2021. The Director for the Dirección de Gestión de la Calidad, Mrs. Cristina Fierro Figueroa and the Director for the Dirección de Postgrado y Postitutulo, Mr. Manuel Roncagliolo Pastene, sent the following mail to the University, informing:
"Nos complace informar que el Consejo de Acreditación del Área de Ciencias de la Agencia de Acreditación ACREDITA CI, ha acordado acreditar el Programa de Magíster en Astrofísica, impartido por la Universidad de Valparaíso , por un período de 7 años, desde el 27 de Marzo de 2014 hasta el 27 de Marzo de 2021. Felicitamos muy sinceramente a todo el cuerpo académico del Programa por tan excelente desempeño, especialmente a su actual Director, Dr. Radostin Kurtev y a todos los miembros del Consejo del Programa, que llevaron adelante el proceso de autoevaluación con fines de acreditación. Saludos cordiales a todos, Atte." Cristina Fierro Figueroa, Directora, Dirección de Gestión de la Calidad; Manuel Roncagliolo Pastene, Director, Dirección de Postgrado y Postítulo.
This extarordinary achievement was accomplished thanks to the intense work undertaken by the Director of the Master in Astrophysics Program, Dr. Radostin Kurtev, and most specially to Dr. Jura Borissova, as well as the rest of the team of academics and administratives who participated in the process.[March 27,2014]
"VLT Spots Largest Yellow Hypergiant Star"
Exotic Binary System revealed from old and new observations
One of the ten largest yellow stars known up to date has been revealed by ESO´s VLT - Very Large Telescope, a rare and remarkable object that is changing very rapidly and that has been caught during a very brief phase of its life. Olivier Chesneau (Observatoire de la Cote d ´Azur, Nice, France) and an international team of Collaborators, amongst them Samer Kanaan, Michel Curé and Catalina Arcos, from the Physics and Astronomy Institute of the U. of Valparaiso, have found that the yellow hypergiant star HR5171 A is absolutely huge, bigger than expected, measuring more than 1300 times the diameter of the Sun, and to be part of a double star system so close that both partners are in contact. The new results obtained by use of Interferometry, a technique that combines the light collected from multiple individual telescopes effectively creating a giant telescope up to 140 metros in size, prompted the team to thoroughly investigate older observations of the star spanning more than sixty years, to see how it behaved in the past.The Spectral data were obtained using the Anglo-Austrian Telescope with the University College London Echelle Spectrograph (UCLES), at the South African Astronomical Observatory (SAAO), through coronographic observations with the Near-Infrared Coronographic Imager (NICI) on the Gemini South Telescope and with PUCHEROS, from the Pontificia Universidad Católica de Chile (PUC) where Samer Kanaan is P.I. Archival photometric datasets examined include infrared photometry from the South African Astronomical Observatory spanning the time frame from 1975 to 2013 and other datasets from 1983 to 202, including some amateur observations in which the agreement of professional results with those of amateur astronomer Sebastian Otero (2000-2013) is considered by authors to be "excellent" and "illustrates the quality of these amateur observations".

To our dear Postdoc, colleague and friend Dr. Gisela Romero
How to write these words without profound emotion? Not knowing where destiny will take us sometimes makes us live hastily, not appreciating fully someone dear, minute by minute...as Time slips by. Gisela was for us kindness itself, genteel and trustworthy, with outstanding sensitivity and human values, and a permanent care for others with that eternal kindness she took with her in her day to day activities among the members and postdocs of the Instituto de Física y Astronomía of the Universidad de Valparaíso. Gisela arrived in 2008 to our Department, sharing with us beautiful experiences and knowledge about the stars she so loved, emotionating us with her own emotion, during the classes and seminars she gave while with us.
We send our affection, care and energies to her colleagues of the Observatorio de La Plata and Instituto de Radioastronomía de Argentina, who shared so much with her, and who will surely miss her too. Our eternal sympathies to her parents, who had the beautiful mission of guiding their daughter along the path she chose, sowing sweetness wherever she went, a quality that was surely part of the lovely home she grew up in.
Gisela, dear "Gisi" for those who where nearest to you, you leave a tender and permanent memory of your human kindness with us and help in difficult times, always present with a word of hope, a "miraculous light in my life" in words of one, a "profound and kind soul" in words of another, an eternal and unforgettable friend for all of us, and someone who will always be near, most specially when we lift up our eyes to the starry sky above.
With love, respect and admiration for you, we will always remember you, Beautiful Post-Doc.[Jan.22, 2014]
