Spitzer IRS Spectroscopy of Intermediate Polars: Constraints on Mid-Infrared Cyclotron Emission (2006)

Harrison, Thomas E., Campbell, Ryan K., Howell, Steve B., Cordova, France A., Schwope, Axel D.

We present Spitzer Infrared Spectrograph (IRS) observations of eleven intermediate polars (IPs). Spectra covering the wavelength range from 5.2 to 14 $\mu$m are presented for all eleven objects, and...

The Nature of the Secondary Star in the Black Hole X-Ray Transient V616 Mon (=A0620-00) (2006)

Harrison, Thomas E., Howell, Steve B., Szkody, Paula, Cordova, France A.

We have used NIRSPEC on Keck II to obtain $K$-band spectroscopy of the low mass X-ray binary V616 Mon (= A0620$-$00). V616 Mon is the proto-typical soft x-ray transient containing a black hole...

Probing the Pulsar Wind Nebula of PSR B0355+54 (2006)

McGowan, Katherine E., Vestrand, W. Tom, Kennea, Jamie A., Zane, Silvia, Cropper, Mark, Cordova, France A.

We present XMM-Newton and Chandra X-ray observations of the middle-aged radio pulsar PSR B0355+54. Our X-ray observations reveal emission not only from the pulsar itself, but also from a compact...

Low State, Phase-Resolved IR Spectroscopy of VV Puppis (2005)

Howell, Steve B., Harrison, Thomas E., Campbell, Ryan K., Cordova, France A., Szkody, Paula

We present phase-resolved low resolution $JHK$ and higher resolution $K$-band spectroscopy of the polar VV Pup. All observations were obtained when VV Pup was in a low accretion state having a K...

Why Are The Secondary Stars in Polars So Normal? (2005)

Harrison, Thomas E., Howell, Steve B., Szkody, Paula, Cordova, France A.

We have used NIRSPEC on Keck II to obtain $K$-band spectroscopy of several magnetic cataclysmic variables. These data reveal that the secondary stars in these binary systems have spectra that are...

X-ray Observations of the Boundary Layer in Dwarf Novae at Low Accretion Rates (2005)

Pandel, Dirk, Cordova, France A., Mason, Keith O., Priedhorsky, William C.

We present a spectral analysis of XMM-Newton data of ten dwarf novae, nine of which were observed during a quiescent state. The X-ray spectra indicate the presence of a hot, optically thin plasma...

X-ray observations of dwarf novae (2005)

Cordova, France A.

NOTE: Text or symbols not renderable in plain ASCII are indicated by [...]. Abstract is included in .pdf document. The details of a survey of the X-ray properties of ~65 dwarf novae are presented:...

Irregular Mass Transfer in the Polars VV Puppis and V393 Pavonis during the Low State (2005)

Pandel, Dirk, Cordova, France A.

The polars VV Pup and V393 Pav were observed with XMM-Newton during states of low accretion rate with peak X-ray luminosities of ~1 x 10^30 and ~1 x 10^31 erg/s, respectively. In both polars,...

FUSE Spectroscopy of the Transitional Magnetic Cataclysmic Variable V405 Aurigae (2004)

Sing, David K., Howell, Steve B., Szkody, Paula, Cordova, France A.

We present Far Ultraviolet Spectroscopic Explorer observations of the magnetic cataclysmic variable V405 Aurigae. Together with four other DQ Her type binaries, V405 Aur forms a small subclass of...

X-ray and UV observations of the dwarf nova VW Hyi in quiescence (2003)

Pandel, Dirk, Cordova, France A., Howell, Steve B.

We present an analysis of X-ray and ultra-violet data of the dwarf nova VW Hyi that were obtained with XMM-Newton during the quiescent state. The X-ray spectrum indicates the presence of an optically...

XMM-Newton Observations of PSR B1706-44 (2003)

McGowan, Katherine E., Zane, Silvia, Cropper, Mark, Kennea, Jamie A., Cordova, France A., Ho, Cheng, ...

We report on the XMM-Newton observations of the young, 102 ms pulsar PSR B1706-44. We have found that both a blackbody plus power-law and a magnetized atmospheric model plus power-law provide an...

Detection of Pulsed X-ray Emission from XMM-Newton Observations of PSR J0538+2817 (2003)

McGowan, Katherine E., Kennea, Jamie A., Zane, Silvia, Cordova, France A., Cropper, Mark, Ho, Cheng, ...

We report on the XMM-Newton observations of the 143 ms pulsar PSR J0538+2817. We present evidence for the first detections of pulsed X-rays from the source at a frequency which is consistent with the...

XMM-Newton observes flaring in the polar UZ For during a low state (2002)

Pandel, Dirk, Cordova, France A.

During an XMM-Newton observation, the eclipsing polar UZ For was found in a peculiar state with an extremely low X-ray luminosity and occasional X-ray and UV flaring. For most of the observation, UZ...

First XMM-Newton observations of strongly magnetic cataclysmic variables - II. Timing studies of DP Leo and WW Hor (2001)

Pandel, Dirk, Cordova, France A., Shirey, Robert E., Ramsay, Gavin, Cropper, Mark, Mason, Keith O., ...

XMM-Newton was used to observe two eclipsing, magnetic cataclysmic variables, DP Leo and WW Hor, continuously for three orbital cycles each. Both systems were in an intermediate state of accretion....

The X-ray Behavior of Two CVs: TT Ari and DP Leo (1993)

Robinson, Craig R., Cordova, France A.

We present ROSAT PSPC observations of the nova-like, or intermediate polar, TT Ari and the eclipsing polar DP Leo. Observations of TT Ari were performed as part of a simultaneous multiwavelength...
