  In the past two decades, it has been convincingly argued that magnetospheric
radio emissions, of cyclotron maser origin, can occur for exoplanetary systems,
similarly as solar planets, with the same periodicity as the planetary orbit.
These emissions are primarily expected at low frequencies (usually below 100
MHz, c.f. Farrell et al., 1999; Zarka, 2007). The radio detection of exoplanets
will considerably expand the field of comparative magnetospheric physics and
star-planet plasma interactions (Hess & Zarka, 2011). We have developed a
prediction code for exoplanetary radio emissions, PALANTIR: "Prediction
Algorithm for star-pLANeT Interactions in Radio". This code has been developed
for the construction of an up-to-date and evolutive target catalog, based on
observed exoplanet physical parameters, radio emission theory, and
magnetospheric physics embedded in scaling laws. It is based on, and extends,
previous work by Grie{\ss}meier et al. (2007b). Using PALANTIR, we prepared an
updated list of targets of interest for radio emissions. Additionally, we
compare our results with previous studies conducted with similar models
(Grie{\ss}meier, 2017). For the next steps, we aim at improving this code by
adding new models and updating those already used.
