Current Activities

Working on the fundamental properties of cataclysmic variables, including abundance analyses, at NMSU, in Las Cruces, New Mexico (a nice view of NM & AZ).

Current Situation

    Here are some new SPEX spectra of CVs:

    Carbon-deficient U Gem

    Carbon & Mg-deficient SS Cyg

    Here are some infrared argon arc lamp spectra (with the vacuum wavelengths of the strongest lines identified) obtained using SPEX:

    J-band (1.0 to 1.2 microns)

    J-band (1.2 to 1.4 microns)

    H-band (1.5 to 1.8 microns)

    K-band (1.98 to 2.4 microns)

    OH lines in the K-band using OSIRIS (2.10 to 2.26 microns)

    DIS arcs:

    B1200, Center = 4500 Å

    R1200, Center = 8200 Å

    R1200, Center = 6300 Å

    (Remember that blue is on the right in raw DIS red spectra)

    Images from our campus observatory Meade 16" telescope with ST8 CCD:

    1) 180s R-band exposure of M42 (unguided, 2X2 binning).

    The initial tracking quality on our 16" was rather poor, after much fiddling, we have reduced this to about 1" r.m.s. Proof is shown in the R-band image of M67, which has an exposure time of 4 minutes (one complete worm revolution).

    2) 240s R-band Exposure of M67 (unguided, raw image).

    3) The Moon (4/1/98).

    3) 240s R-band Exposure of M51 (unguided).
