Efficient analysis in planet transit surveys
A. Schwarzenberg-Czerny, J. -Ph. Beaulieu
With the growing number of projects dedicated to the search for extrasolar planets via transits, there is a need to develop fast, automatic, robust methods with a statistical backg…
The Long-Term H Emission Line Variation in Eri
M. M. F. Vinicius, Nelson Vani Leister, Juan Zorec +1
The long-term variation of the H line in Eri has 14-15 years cyclic \bbe phase transitions. The disc formation time scales, interpreted as the periods during which the H…
Fast Rotation vs. Metallicity
Ronaldo Levenhagen, Nelson Vani Leister, Juan Zorec +1
Fast rotation seems to be the major factor to trigger the Be phenomenon. Surface fast rotation can be favored by initial formation conditions such as metal abundance. Models of fas…
Properties of Regions Forming the FeII Emission Lines in Be Stars
Maria Laura Arias, Juan Zorec, Lydia Cidale +1
We study FeII and Balmer hydrogen emission lines observed simultaneously of 18 southern Be stars. We use the self-absorption-curve method (SAC) to determine the optical depth regim…
Zams Rotational Velocities of be Stars
Juan Zorec, Christophe Martayan, Yves Fremat +2
We show that Be stars belong to a high velocity tail of a single B-type star rotational velocity distribution in the main sequence (MS). We studied 127 galactic field Be stars and…
Achernar Can be a Differential Rotator
Juan Zorec, Armando Domiciano De Souza, Yves Fremat +1
We take advantage of interferometric measurements of Achernar to inquire on its internal rotational law. The reinterpretation of interferome-tric data and the use of fundamental pa…
