Estimadas y estimados colegas,

Nos ponemos en contacto con ustedes para invitarlas/os a un Ciclo de 
Seminarios que estamos organizando para que las comunidades astronómicas 
de Argentina y Brasil empiecen a tomar contacto con el proyecto LLAMA.

LLAMA (Large Latin American Millimeter Array) es un radiotelescopio de 
12 metros de diámetro  cuya construcción está siendo llevada a cabo por 
Argentina y Brasil y será puesto en marcha en la provincia de Salta, a 
una altura de 4.830 msnm.
El instrumento podrá observar en distintas bandas (B1-B9 simil ALMA), 
cubriendo un rango de frecuencias de 35–950 GHz (longitudes de onda 
milimétricas y submilimétricas).

El objetivo principal de estos encuentros es difundir las novedades 
sobre LLAMA, discutir la ciencia que podrá llevarse a cabo  y  motivar 
la comunicación e interacción entre investigadores y estudiantes de las 
distintas áreas de la astronomía.

*El Ciclo de Seminarios LLAMA tendrá lugar los primeros viernes de cada 
mes, de 10 a 12 hs, en formato virtual.*
Cada encuentro consistirá de 3 charlas invitadas (la primera de 40 
minutos de duración y las otras dos de 20 minutos cada una) e intervalos 
para discusiones.

*El primer encuentro será el viernes 4 de junio de 2021*, *con el 
siguiente cronograma:*

*10:00 hs: Félix Mirabel* (IAFE, Buenos Aires, Argentina) *

*The origin of project LLAMA*
**Abstract: I have been asked to talk on the origin of project LLAMA 
(Large Latin American  Millimeter Array).
By personal initiative in 1984 I make the first exploration in the Puna 
of Salta, Jujuy and Catamarca for the installation of the European 
project LSA (Large  Submillimetre Array).  Sites in Macon and near San 
Antonio de los Cobres among others are identified in the province of 
Salta. In the 1990’s  LSA  merged  with the Nord American project MMA 
(Milli-meter Array) in the global project ALMA (Atacama Large Millimeter 
Array) to be installed in Chajnantor, Chile. In the period 2004-2009, 
being Representative and Director of the Office of Science of the 
European Southern Observatories (ESO) in Chile, I propose to the 
director of ALMA, the head of MinCyT (Ministry of Science & Technology 
of Argentina), Jacques Lepine and Zulema Abraham (University of Sao 
Paulo) project LLAMA. In 2014 it is signed an agreement between MinCyT 
and FAPESP for the construction and operation of LLAMA.
A personal view on this subject can be found (in spanish) in pages 67-69

*11:00 hs: Zulema Abraham* (IAG, Universidade de São Paulo, Brasil)
*Eta Carinae : a perfect target for LLAMA*
**Abstract:  Eta Carinae is one of the most massive stars of our Galaxy. 
It is an evolved star that presented several episodes of mass ejection, 
one of them
occurred in 1840 and formed what is now known as the Homunculus Nebula. 
Eta Carinae is part of a binary system, in which the collision between the
strong stellar winds heats the gas that emits in X-rays. The UV 
radiation of the stars ionizes the circumstellar matter, producing 
radiation from the
UV to radio frequencies. At mm and sub-millimeter wavelengths, strong 
continuum and H recombination lines have been observed since 1995, but 
the actual source was only resolved by ALMA in 2017. I will present the 
results of these ALMA observations and show the importance of LLAMA for 
the follow up of the continuum and recombination lines at different 
frequencies to understand its variability with the orbital phase of the 
binary system.

*11:30 hs: Lydia Cidale* (FCAGLP, La Plata, Argentina) *
*
*Dust and gaseous environments around massive stars*
Abstract: Evolved massive stars undergo phases of strong mass-loss, 
often resulting in the formation of shells, disks or rings of 
circumstellar material. The expelled material can lead to molecule and 
dust condensation. Studies of the atomic and molecular gas reveal  a 
complex kinematics and geometry. We describe here different techniques 
to analyze and interpret the physical conditions around  hot 
emission-line stars.
