Aims. We challenge the accepted distance of 3.2 kpc of GRO J1655-40. We present VLT-UVES spectroscopic observations to estimate the absorption toward the source, and determine a maximum distance of GRO J1655-40. Methods. We show that the accepted value of 3.2 kpc is taken for granted by many authors. We retrieved in the ESO archive UVES spectra taken in April 2004 when GRO J1655-40 was in quiescence to determine the spectral type of the secondary star. For the first t ime we build a flux… 
Are the distances of galactic microquasars reliable
We review some specific and quantitative issues in popular me thods used to determine the distance of galactic objects, in the context of the microquasar s GRO J1655-40 and 1A 0620-00. In particular,
On the abundances of GRO J1655-40
Context. The detection of overabundances of α-elements and lithium in the secondary star of a black-hole binary provides important insights about the formation of a stellar-mass black-hole.
What is the closest blackhole to the sun ? I
We examine the question of the distance of the two galactic microquasars GRO J1655–40 and A 0620–00 which are potentially the two closest black-holes to the Sun. We aim at providing a picture as wide
The rise and fall of the compact jet in GRO J1655-40
In this work, we present some preliminary results on a multi-wavelength (radio/infrared/optical/X-ray) study of GRO J1655-40 during its 2005 outburst. We focus on the broadband spectral energy
What is the closest black hole to the Sun
Abstract We examine the distance of the two galactic microquasars GRO J1655–40 and A 0620–00 which are potentially the two closest black holes to the Sun. We aim to provide a picture as wide and
New evidence on the origin of the microquasar GRO J1655-40
Aims. Motivated by the new determination of the distance to the microquasar GRO J1655−40 by Foellmi et al. (2006, A&A, 457, 249), we conduct a detailed study of the distribution of the atomic (HI)
The highly ionized disk wind of GRO J1655-40
Aims. The galactic superluminal microquasar GRO J1655-40 started a new outburst in February 2005, after seven years in quiescence, rising to a high/soft state in March 2005. In this paper we study

The 1996 outburst of GRO J1655-40 I: The challenge of interpreting the multi-wavelength spectra
We report on the results of a multiwavelength campaign to observe the soft X-ray transient (SXT) and superluminal jet source GRO J1655-40 in outburst using HSTRXTECGRO together with ground-based
The optical counterpart of the superluminal source GRO J1655 – 40
THE accretion of gas from a companion star onto a compact object, such as a neutron star or black hole, can release large amounts of energy. Episodic accretion is generally thought to explain
The quiescent light curve and the evolutionary state of GRO J1655–40
We present ellipsoidal light-curve fits to the quiescent B, V, R and I light curves of GRO J1655–40 (Nova Scorpii 1994). The fits are based on a simple model consisting of a Roche-lobe-filling
The mass of x-ray Nova Scorpii 1994 GRO J1655-40
TLDR
The radial velocity curve of the secondary star is measured and a semi-amplitude of K2 is obtained, which reduces the binary mass function to f(M) = 2.73 ± 0.09 M⊙.
