Abstract:
RW Aur A is a classical T Tauri star that has suddenly undergone three
major dimming events since 2010. The reason for these dimming events
is still not clear. The two epochs of observations uploaded here are
on the deep dimming events (2015) and immediate after the dimmin event
(2016).
Description:
X-Shooter spectra from the UV to the NIR wavelengths (∼300-2400nm).
There are two epochs of data on in March 2015 (294.C-5047) and the
other one in September 2016(098.C-0922(A)). For both observing runs, a
set of large (1.6x11", 1.5x11",1.2x11") and narrow (0.5x11", 0.4x11",
0.4x11") slits were used in the UVB, VIS, and NIR arms, respectively.
The spectra are telluric corrected and flux calibrated. All the fits
files have wavelength in nanometers and flux in ergs/s/cm2/nm
