Abstract
Irregular variables of type Lb share many characteristics with asymptotic giant branch (AGB) stars such as Miras and semiregulars (SRs). Despite their large number, irregulars are poorly understood. Using the large Nan�ay radio telescope, we searched for 18-cm OH maser emission from these stars. We selected two samples of Lbs that present a noticeable circumstellar envelope. In the first one, 44 high-latitude objects with infrared colours of dusty mass-losing stars were observed in a wide-bandwidth velocity-search mode. In addition, 16 objects (including six from the first sample), in which other circumstellar molecular lines had recently been found, were observed with higher resolution and sensitivity. We did not detect any new OH maser emission from these samples down to 3sigma sensitivity limits ranging from 30 to 200 mJy. We derived upper limits for the efficiency of a typical pump using far-infrared photons. When compared with known OH masers in AGB stars, we show that a significant gap is left unexplored below the threshold that we determined for Lbs. Lower efficiencies exist in some OH Miras and in the OH SRs. We cannot discard the possibility of faint OH emission from certain Lbs, based on the same processes as encountered in those sources. We briefly discuss physical conditions allowing OH emission in the envelope, and the evolutionary stage of objects classified as Lb variables with respect to the AGB.

Abstract

Irregular variables of type Lb share many characteristics with asymptotic giant branch (AGB) stars such as Miras and semiregulars (SRs). Despite their large number, irregulars are poorly understood. Using the large Nan�ay radio telescope, we searched for 18-cm OH maser emission from these stars. We selected two samples of Lbs that present a noticeable circumstellar envelope. In the first one, 44 high-latitude objects with infrared colours of dusty mass-losing stars were observed in a wide-bandwidth velocity-search mode. In addition, 16 objects (including six from the first sample), in which other circumstellar molecular lines had recently been found, were observed with higher resolution and sensitivity. We did not detect any new OH maser emission from these samples down to 3sigma sensitivity limits ranging from 30 to 200 mJy. We derived upper limits for the efficiency of a typical pump using far-infrared photons. When compared with known OH masers in AGB stars, we show that a significant gap is left unexplored below the threshold that we determined for Lbs. Lower efficiencies exist in some OH Miras and in the OH SRs. We cannot discard the possibility of faint OH emission from certain Lbs, based on the same processes as encountered in those sources. We briefly discuss physical conditions allowing OH emission in the envelope, and the evolutionary stage of objects classified as Lb variables with respect to the AGB.

Distribution of sources in all sky (l,b)

Distribution of sources in all sky using Aladin

Tip: Click on some source to get more informaiton

Distribution of sources in IRAS color-color diagram

Tip: Use "Box select" or "Lasso select" to display colour-selected sources in Aladin all-sky view

Tip: Click on some source to look at the different surveys. You must select some surveys in previous page at "View images"

Original color diagram is taken form van der Veen & Habing (1987)

Type	Description
I	Oxygen-rich non-variable stars without circumstellar shells
II	Variable stars with "young" O-rich circumstellar shells
IIIa	Variable stars with more evolved O-rich circumstellar shells
IIIb	Variable stars with thick O-rich circumstellar shells
IV	Variable stars with very thick O-rich circumstellar shells
V	Planetary nebulae and non- variable stars with very cool circumstellar shells
VIa	Variable stars with relatively cold dust at large distances; a significant part of the stars is carbon-rich
VIb	Variable stars with relatively hot dust close to the star and relatively cold dust at large distances; Some of the objects have proven to be O-rich
VII	Variable stars with more evolved C-rich circumstellar shells
VIII	Different sort of objects
