Types of Presentations

Research Contributed Presentations

    • Research Contributed Oral Presentations
    • Research Contributed Poster Presentations

The number of oral presentation time slots are limited. Oral abstracts submissions may be changed to posters if there are no remaining slots - this is at the discretion of the SOC.


    • Presenters must be listed as the first author on the paper at the time of submission.
    • The presenting/first author must be the one to make the submission.
    • Presenting/first author must register for the meeting.
    • All abstracts must be submitted through the abstract submission system.

Abstracts per Meeting

You may submit the following abstracts per meeting:

    • 1 oral OR poster abstract


    • If an author is unable to attend, his or her abstract will be presented by title only. The abstract will still be published in the Astrophysics Data System (ADS) and in the meeting abstract publication. Notify the abstract help desk if an author cannot attend.
    • In the case of severe physical misfortune, a joint abstract may be presented by a co-author, even if the co-author is presenting another abstract. The original author must email the request to the abstract help desk, making an explicit statement of the cause.


We will strictly adhere to the following deadlines:

    • The deadline for receipt of regular abstracts is 30 May 2019 at 9:00 pm ET/1:00 am GMT 31 May 2019.
    • The deadline for receipt of late-breaking abstracts is 11 July, 2019 at 9:00 pm ET/1:00 am GMT 12 July 2019

Edits to Abstracts

    • We understand that edits sometimes need to be made to abstracts after they are submitted. We try hard to accommodate edits and changes as we lead up to the conference, but due to certain publishing deadlines we will be unable to edit abstracts starting four weeks before the meeting start date.

Publication of Abstracts

The meeting and abstract schedule are published in various formats:

    • Paper Final Program - Distributed at the meeting; includes abstract titles.
    • Online PDF of Abstracts - Available two weeks prior to the meeting; includes full abstract text.
    • Astrophysics Data System (ADS) - Abstracts are sent to ADS and typically published two week prior to the meeting. 

Submission Process

Abstracts must be submitted through the online system. Co-authors are not eligible to substitute as the presenting author. The presenting author will be notified once the schedule has been determined.

Abstract Form Details

The form contains instructions on the various steps required to complete a submission. Once you have completed the Title Step you are assigned a control number and may exit and re-enter the system.

    • The abstract must be complete and submitted by the deadline, 30 May 2019 at 9:00 pm ET/1:00 am GMT 31 May 2019.
    • The abstract body text can be a maximum of 2,250 characters (which includes letters, numbers, punctuation, spacing, returns and symbols/special characters).
    • To enter co-authors, you must have the following: full first and last name, e-mail address and affiliation. 
    • You can continue to make changes to your abstract before the deadline, 30 May 2019. To edit an abstract, click the "Return to Draft" button. This will return the abstract to draft status, allowing you to make further edits to the abstract. Please remember to re-submit the abstract before the deadline.

To switch the presenting author to a co-author you must submit a new abstract by logging in as the new presenting author.

Presentation Guidelines and Tips

Poster Presentations


Posters allow far more time and flexibility and are the default presentation type. Posters are ideal for using charts, graphs or detailed visual aids. The poster area serves as the meeting’s social center.

    • Your poster can be no larger 95cm wide x 150cm tall (portrait-orientation).
    • Poster abstracts are displayed by topic.
    • The poster presentation schedule will be determined by the SOC. 


    • When preparing your poster, remember to use bold graphs, photographs, figures, and tables. Include a title and the names of authors in large type. Text should be large enough to be legible from a distance of three to four feet, ~ 20 point font. Keep the poster simple and easy to read. 
    • There is a good article on preparing an eye-catching poster at, Presentations: Billboard Science.
    • Consider posting a photo of yourself with your presentation.

Oral Presentations


To avoid oral sessions running simultaneously, the number of oral presentation time slots is limited. Oral presentations may be changed to posters if there are no remaining slots, at the discretion of the SOC.

    • Presentations should be prepared in the 16:9 format.
    • Laptops will have Microsoft Office and Keynote presentation software.
    • Sound will be enabled at the presentation laptop for videos.


    • Slides should be uncluttered and easy to read.
    • Practice a few times so the presentation fits comfortably into the allotted time slot.
