Descripción
High-speed photometric observations of the recently discovered roAp star
10 Aql were performed in the J(1.22-micrometer) filter. A total of 47.2
hours of data were obtained during seven consecutive nights in July
1990, using a standard infrared photometer attached to the Cassegrain
focus of the 1.54 m Carlos Sanchez telescope at the Observatorio del
Teide (Tenerife, Spain). As a first approach, the harmonic analysis of
the data shows a noise level of about 0.8 mmag with the presence of
marginal signal (Delta-J is approximately equal to 1 mmag) in the
visible (B band) photometric frequencies already reported by Heller and
Cramer (1990). The possibility of interpreting these events as actual
stellar signal is discussed.
