The N2H+ envelope is a thick clumpy torus with a tenuous outer part and a ringlike dense inner edge. The dense inner edge has a mean radius of 10'', or 1400 AU.

The two continuum sources are located in the southeast–northwest direction, with total gas masses of ∼0.011 M and ∼0.005 M , respectively.

IRAM 041911+1522 is a low-luminosity (∼0.08 L e ) protostar (Dunham et al. 2006) . André et al. (1999) found the highly collimated CO outflow, and they ...

Abstract. We present high angular resolution observations of the Class 0 protostar IRAM 04191+1522 using the Submillimeter Array (SMA).

We have carried out mapping observations of the molecular core associated with the young Class 0 protostar, IRAM 04191+1522, in the CH3OH (JK=2K-1K) and C34S...

However, high resolution observations of the IRAM 04191+1522 protostar have shown a significant depletion of N2H+ and NH3 in its core. IRAM 04191+1522, a class ...

We present a detailed millimeter spectroscopic study of the circumstellar environment of the low-luminosity Class 0 protostar IRAM 04191+1522 in the Taurus ...

In this paper, we investigate the protostellar collapse and outflow in the second and third stages, by observing one of the youngest protostars, IRAM. 04191+ ...

We aim to explore whether or not the observed C 18 O and N 2 H + emission pattern towards the VeLLO IRAM 04191+1522 can be understood.
