The Planets-Capture Model of V838 Monocerotis (2006)
Retter, Alon, Zhang, Bing, Siess, Lionel, Levinson, Amir, Marom, Ariel
The planets capture model for the eruption of V838 Mon is discussed. We used three methods to estimate the location where the planets were consumed. There is a nice consistency for the results of the...
Interferometric Observations of Explosive Variables: V838 Mon, Nova Aql 2005, and RS Oph (2006)
Lane, Benjamin F., Retter, Alon, Eisner, Joshua A., Thompson, Robert R., Muterspaugh, Matthew W.
During the last two years we have used the Palomar Testbed Interferometer to observe several explosive variable stars, including V838 Monocerotis, V1663 Aquilae and recently RS Ophiuchi. We observed...

V838 Mon is the prototype of a new class of objects. Understanding the nature of its multi-stage outburst and similar systems is challenging. So far, several scenarios have been invoked to explain...
V4745 Sgr -- a nova above the period gap and an intermediate polar candidate (2006)
Dobrotka, Andrej, Retter, Alon, Liu, Alex
A period analysis of CCD unfiltered photometry of V4745 Sgr (Nova Sgr 2003 #1) performed during 23 nights in the years 2003 - 2005 is presented. The photometric data are modulated with a period of...
Nova V4743 Sagittarii 2002: An Intermediate Polar Candidate (2006)
Kang, Tae W., Retter, Alon, Liu, Alex, Richards, Mercedes
We present the results of 11 nights of CCD unfiltered photometry of V4743 Sgr (Nova Sgr 2002 # 3) from 2003 and 2005. We find two periods of 0.2799 d ~ 6.7 h and 0.01642 d ~ 24 min in the 2005 data....

The Swift X-ray flaring afterglow of GRB 050607 (2006)
Pagani, Claudio, Morris, David C., Kobayashi, Shiho, Sakamoto, Takanori, Falcone, Abraham D., Moretti, Alberto, ...
The unique capability of the Swift satellite to perform a prompt and autonomous slew to a newly detected Gamma-Ray Burst (GRB) has yielded the discovery of interesting new properties of GRB X-ray...
Swift Observations of GRB 050603: An afterglow with a steep late time decay slope (2006)
Grupe, Dirk, Brown, Peter, Cummings, Jay, Zhang, Bing, Retter, Alon, Burrows, David N., ...
We report the results of Swift observations of the Gamma Ray Burst GRB 050603. With a V magnitude V=18.2 about 10 hours after the burst the optical afterglow was the brightest so far detected by...
Imada, Akira, Kato, Taichi, Monard, L. A. G., Retter, Alon, Liu, Alex, Nogami, Daisaku
We report on time-resolved photometry of the 2005 July superoutburst of the dwarf nova, 2QZ J021927.9-304545. The resultant light curves showed conspicuous superhumps with a period of 0.081113(19)...
Balman, Solen, Retter, Alon, Bos, Marc
We present CCD photometry, light curve and time series analysis of the classical nova V382 Vel (N Vel 1999). The source was observed for 2 nights in 2000, 21 nights in 2001 and 7 nights in 2002 using...

Detection of orbital and superhump periods in Nova V2574 Ophiuchi (2004) (2005)
Kang, Tae W., Retter, Alon, Liu, Alex, Richards, Mercedes
We present the results of 37 nights of CCD unfiltered photometry of nova V2574 Oph (2004) from 2004 and 2005. We find two periods of 0.14164 d (~3.40 h) and 0.14773 d (~3.55 h) in the 2005 data. The...
The possible orbital period of the nova V1493 Aquilae (2005)
Dobrotka, Andrej, Friedjung, Michael, Retter, Alon, Hric, Ladislav, Novak, Rudolf
Period analysis of CCD photometry of V1493 Aql (Nova Aql 1999 no. 1) performed during 12 nights through I and R filters a few weeks after maximum is presented. The PDM method for period analysis...
Retter, Alon, Richards, Mercedes T., Wu, Kinwah
Extensive radio data of two Algol systems and two RS CVn binaries were re-analyzed. We found evidence for a new periodicity that we interpret as a superhump in Algol, in which it may have been...
Constraining jet theories using nova outbursts (2004)
It is commonly accepted that jets have not been observed in CVs so far. This absence was recently explained by their low mass transfer rates compared with objects with jets. A mass accretion limit...
Evidence for large superhumps in TX Col and V4742 Sgr (2004)
Retter, Alon, Liu, Alexander, Bos, Marc
Since the discovery of the largest positive superhump period in TV Col, we have started a program to search for superhumps in CVs with large orbital periods. Here, we summarize preliminary results of...
A Tight Upper Limit on Oscillations in the Ap star Epsilon Ursae Majoris from WIRE Photometry (2003)
Retter, Alon, Bedding, Timothy R., Buzasi, Derek L., Kjeldsen, Hans, Kiss, Laszlo L.
Observations of Epsilon UMa obtained with the star tracker on the Wide Field Infrared Explorer (WIRE) satellite during a month in mid-2000 are analyzed. This is one of the most precise photometry of...

Littlefair, S. P., Naylor, Tim, Harries, Tim J., Retter, Alon, O'Toole, S.
We have discovered T Tauri stars which show startling spectral variability between observations seperated by 20 years. In spectra published by Bouvier & Appenzeller (1992) these objects showed very...
A model of an expanding giant that swallowed planets for the eruption of V838 Monocerotis (2003)
In early 2002 V838 Monocerotis had an extraordinary outburst whose nature is still unclear. The optical light curve showed at least three peaks and imaging revealed a light echo around the object -...
Erratum: "Oscillations in Arcturus from WIRE photometry" (ApJ, 591, L151 [2003]) (2003)
Retter, Alon, Bedding, Timothy R., Buzasi, Derek L., Kjeldsen, Hans, Kiss, László L.
The value of the mode lifetime given in the first paragraph of the Discussion should be divided by 2pi and is therefore 2.0 days rather than 13 days.
