Modification of AGB wind in a binary system
Adam Frankowski, Romuald Tylenda
We explore one of plausible causes of asymmetry in the wind of an AGB star - the presence of a binary companion. We have developed a simple method for estimating the intrinsic non-…
NGC 300 OT2008-1 As a Scaled-Down Version of the Eta Carinae Great Eruption
Amit Kashi, Adam Frankowski, Noam Soker
We propose that the intermediate luminosity optical transient NGC 300 OT2008-1 was powered by a mass transfer episode from an extreme Asymptotic Giant Branch star to a Main Sequenc…
Lithium in coalesced non-compact stars
Tomek KamiÅski, Mirek Schmidt, Marcin Hajduk +3
Context. Galactic red novae are thought to be produced in stellar mergers between non-compact stars, such as main-sequence stars and cool giants. They are hoped to help in explaini…
Comparing Symbiotic Nebulae and Planetary Nebulae Luminosity Functions
Adam Frankowski, Noam Soker
We compare the observed symbiotic nebulae (SyN) luminosity function (SyNLF) in the [O III] 5007A line to the planetary nebulae (PN) luminosity function (PNLF) and find that the int…
Energy-dependent orbital modulation of X-rays and constraints on emission of the jet in Cyg X-3
Andrzej A. Zdziarski, Chandreyee Maitra, Adam Frankowski +2
We study orbital modulation of X-rays from Cyg X-3, using data from Swift, INTEGRAL and RXTE. Using the wealth of the presently available data and an improved averaging method, we…
Very Late Thermal Pulses Influenced by Accretion in Planetary Nebulae
Adam Frankowski, Noam Soker
We consider the possibility that a mass of ~10^{-5}-10^{-3} Msun flows back from the dense shell of planetary nebulae and is accreted by the central star during the planetary nebul…
The puzzling case of 56 Pegasi: A fast rotator seen nearly face-on?
Adam Frankowski, Alain Jorissen
A spectroscopic orbit has been recently found by R. Griffin for the long known barium star 56 Peg, which is also a strong X-ray source. This short-period, low mass-function orbit r…
V838 Monocerotis as seen by ALMA: a remnant of a binary merger in a triple system
Tomek KamiÅski, Romuald Tylenda, Aleksandra Kiljan +6
V838 Mon erupted in 2002 quickly becoming the prototype of a new type of stellar eruptions known today as (luminous) red novae. The red nova outbursts are thought to be caused by s…
Performance of the Cherenkov Telescope Array at energies above 10 TeV
Anna Barnacka, Leszek Bogacz, Mira GrudziÅska +4
The Cherenkov Telescope Array (CTA) is the next generation observatory for very high energy gamma rays. The capability of the array to detect gamma-rays above 10 TeV is going to be…
A comprehensive study of high-energy gamma-ray and radio emission from Cyg X-3
Andrzej A. Zdziarski, Denys Malyshev, Guillaume Dubus +6
We study high-energy -rays observed from Cyg X-3 by the Fermi Large Area Telescope and the 15-GHz emission observed by the Ryle Telescope and the Arcminute Microkelvin Imager.…
Galactic vs. Extragalactic Origin of the Peculiar Transient SCP 06F6
Noam Soker, Adam Frankowski, Amit Kashi
We study four scenarios for the SCP 06F6 transient event that was announced recently. Some of these were previously briefly discussed as plausible models for SCP 06F6, in particula…
An innovative silicon photomultiplier digitizing camera for gamma-ray astronomy
Matthieu Heller, Enrico Junior Schioppa, Alessio Porcelli +44
The single-mirror small-size telescope (SST-1M) is one of the three proposed designs for the small-size telescopes (SSTs) of the Cherenkov Telescope Array (CTA) project. The SST-1M…
