eHOPS (data available)

The Extension of HOPS Out to 500 ParSecs (eHOPS) project used archival data to survey all the major star forming molecular clouds within 500 pc of the Sun, except Orion (which was surveyed by HOPS). The first eHOPS data release covers the Aquila molecular clouds (d ~ 436 pc). For every source detected in the Herschel/PACS bands, the eHOPS-Aquila catalog contains 1-850 micron SEDs assembled from 2MASS, Spitzer, Herschel, WISE, and JCMT/SCUBA-2 data. A total of 172 protostars are found in Aquila, tightly concentrated in the molecular filaments that thread the clouds. Of these, 71 (42%) are Class 0 protostars, 54 (31%) Class I protostars, 43 (25%) are flat-spectrum protostars, and 4 (2%) are Class II sources. Ten of the Class 0 protostars are young PACS Bright Red Sources similar to those discovered in Orion. eHOPS compares the SEDs to a grid of radiative transfer models to constrain the luminosities, envelope densities, and envelope masses of the protostars.

The data can be found at:  https://irsa.ipac.caltech.edu/data/Herschel/eHOPS/ehops_seds_protostars.html


If you use eHOPS data, please cite both the journal article Pokhrel et al. (2023) and the dataset Digital Object Identifier (DOI): 10.26131/IRSA553.







SPEXODISKS (data available)

Dear community of disk observers and modelers,

New dates and open registration for the Hartmann-fest

New dates and open registration for "Star Formation: From Clouds to Discs - A tribute to the career of Lee Hartmann"

In light of the easing of travel restrictions expected in the coming months, the organizers of the conference 'Star Formation: From Clouds to Discs', in honor of the career of Lee Hartmann, have decided to postpone the conference by two more months, to allow more participants to be able to attend in person. The conference will now go ahead from the 18th to 21st of October, 2021, in a hybrid format, including a mix of online and in-person talks and discussions. Due to the ongoing restrictions, the number of participants able to attend in person at the Grand Hotel Malahide, in Dublin, Ireland, will be limited according to Irish government and health authority guidelines.

Abstract submission (with the option of proposing a contribution either virtually or in-person) and registration are now open. The abstract submission deadline is 18th July, 2021. Early-bird registration ends on 18th August, 2021, while late registration for in-person attendance will be open until 18th September, 2021. We look forward to seeing you there.

Start of Pre-Registration Protostars & Planets VII

Pre-registration is now available for Protostars and Planets VII meeting that is postponed about one year from the original schedule. (The original announcement was shown in Star Formation Newsletter No. 321.) This is NOT an official registration and you still need to sign up for the official registration when it is announced.


With this pre-registration, organizers will make a mailing list, to which announcements related to the conference will be posted. The organizers would also like to make an estimate of the number of potential participants to prepare the meeting. It should take only 3 minutes. Please visit the following website:


http://ppvii.org/pre-registration/index.html


Along with the pre-registration, we would like to collect your current intention of (a) the style of participation and (b) poster presentation. Currently, the organizers are planning to hold the conference in 21st - 27th March 2022 on-site in Kyoto. The organizers think that creative and active discussion in person will play an important role in conferences in general, and in particular for Protostars and Planets VII, as critical discussion on each review talk will greatly improve the quality of the PPVII Book that will be published after the meeting. We would like to create a book that would remain as a standard textbook for the next decade.

Thank you.

The SFN is moving from Hawaii to Vienna

Over the next months, the SFN will move from Hawaii to Vienna. Over the transition period, that will take the SFN from PDF based to web based, some things will likely break. If you find problems, incorrect or missing information, or have suggestions on how to improve the SFN web, don't hesitate to send me a message.
